Update 3/26: 2 new names have been added to the voting list – Zeus and Vulcan ![/caption]

United Launch Alliance (ULA) is asking the public for your help in naming their new American made rocket, now under development that “represents the future of space”- and will replace the firms current historic lines of Atlas and Delta rocket families that began launching back near the dawn of the space age.

Eagle, Freedom or GalaxyOne – those are the names to choose from for the next two weeks, from now until April 6.

UPDATE 3/26: 2 new names have been added to the voting list – Zeus and Vulcan !

ULA says the names were selected from a list of over 400 names submitted earlier this year by ULA’s 3400 employees and many space enthusiasts.

ULA has set up a simple voting system whereby you can vote for your favorite name via text or an online webpage.

Currently dubbed the “Next Generation Launch System,” or NGLS, ULA’s new president and CEO Tory Bruno is set to unveil the next generation rockets design and name at the National Space Symposium on April 13 in Colorado Springs, Colorado.

“ULA’s new rocket represents the future of space – innovative, affordable and reliable,” said Bruno, in a statement.

“More possibilities in space means more possibilities here on earth. This is such a critical time for space travel and exploration and we’re excited to bring all of America with us on this journey into the future.”

The NGLS is ULA’s response to what’s shaping up as a no holds barred competition with SpaceX for future launch contracts where only the innovative and those who dramatically cut the cost of access to space will survive.

The first flight of the NGLS is slated for 2019.

Here’s how you can cast your vote for America’s next rocket to April 6, 2015:

Voters can text 22333 to submit a vote for their favorite name. The following key can be used to text a vote:

• ULA1 for “Eagle”
• ULA2 for “Freedom”
• ULA3 for “GalaxyOne”

3/26 Update: Zeus and Vulcan have been added to the voting list

One small step for ULA, one giant leap for space exploration. Vote to name America’s next ride to space: Eagle, Freedom, or GalaxyOne? #rocketvote http://bit.ly/rocketvote

“Name America’s next ride to space. Vote early, vote often … ” says Bruno.

I have already voted – early and often.

Over 11,000 votes were tallied in just the first day.

Currently ULA is the nation’s premier launch provider, launching at a rate of about once per month. 13 launches are planned for 2015- as outlined in my earlier article here.

But ULA faces stiff and relentless pricing and innovative competition from NewSpace upstart SpaceX, founded by billionaire Elon Musk.

NGLS is ULA’s answer to SpaceX – they must compete in order to survive.

To date ULA has accomplished a 100 percent mission success for 94 launches since the firms founding in 2006 as a joint venture between Boeing and Lockheed Martin. They have successfully launched numerous NASA, national security and commercial payloads into orbit and beyond.

Planetary missions launched for NASA include the Mars rovers and landers Phoenix and Curiosity, Pluto/New Horizons, Juno, GRAIL, LRO and LCROSS.

ULA’s new rocket will launch from this pad in 2019

ULA’s most recent launch for NASA involved the $1.1 Billion Magnetospheric Multiscale (MMS) mission comprised of four formation flying satellites which blasted to Earth orbit atop an Atlas V rocket from Cape Canaveral Air Force Station, Florida, during a spectacular nighttime blastoff on March 12, 2015. Read my onsite reports – here and here.

“Space launch affects everyone, every day, and our goal in letting America name its next rocket is to help all Americans imagine the future of endless possibilities created by affordable space launch,” Bruno added.

NGLS will include some heritage design from the Atlas V and Delta IV rockets, but will feature many new systems and potentially some reusable systems – to be outlined by Bruno on April 13.

ULA plans to phase out the Delta IV around 2019 when the current contracts are concluded. The Atlas V will continue for a transitional period.

The Atlas V is also the launcher for Boeing’s CST-100 manned space taxi due to first launch in 2017.

NGLS will launch from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida, the same pad as for the Atlas V, as well as from Vandenberg AFB, Calif.

ULA’s next Delta IV launch with GPS IIF-9 is scheduled shortly for Wednesday, March 25, with liftoff at 2:36 p.m. EDT from Cape Canaveral.

Most Powerful Solid Rocket Booster Ignites in Milestone Test, Propelling NASA on Path to Deep Space

At the Orbital ATK test facility, the booster for NASA’s Space Launch System rocket was fired for a two minute test on March 11. The test is one of two that will qualify the booster for flight before SLS begins carrying NASA’s Orion spacecraft and other potential payloads to deep space destinations. Image Credit: NASA

KENNEDY SPACE CENTER, FL – NASA’s goal of sending humans back to deep space in the next decade advanced a major step forward today, March 11, with the successful ground test firing of the largest and most powerful solid rocket booster ever built that will be used to propel NASA’s Space Launch System (SLS) rocket and manned Orion spacecraft to destinations including the Moon, Asteroids and Mars.

The two minute long, full duration static test firing of the motor marked a major milestone in the ongoing development of NASA’s SLS booster, which is the most powerful rocket ever built in human history.

The booster known as qualification motor, QM-1, is the world’s largest solid rocket motor and was ignited at about 11:30 a.m. EST by prime contractor Orbital ATK at the newly merged firms test facility in Promontory, Utah.

It burned for exactly the same amount of time as it will during flights of the SLS booster which will lift off from Launch Complex 39B at the Kennedy Space Center in Florida.

The booster test firing was the second of two major do or die tests conducted by NASA in the past three months in support of the agency’s “Journey to Mars” strategy to develop the infrastructure required to send astronauts to an asteroid in the next decade and beyond to the Red Planet in the 2030s.

“The work being done around the country today to build SLS is laying a solid foundation for future exploration missions, and these missions will enable us to pioneer far into the solar system,” said William Gerstenmaier, NASA’s associate administrator for human exploration and operations, in a statement.

“The teams are doing tremendous work to develop what will be a national asset for human exploration and potential science missions.”

The 5-segment booster produces 3.6 million lbs of maximum thrust which equates to more than 14 Boeing 747-400s at full takeoff power!

The new 5-segment booster was derived from the 4-segment booster used during NASA’s three decade long Space Shuttle program. One segment has been added and therefore the new, longer and more powerful booster must be requalified to launch the SLS and humans.

A second test is planned a year from now and will qualify the boosters for use with the SLS.

“This test is a significant milestone for SLS and follows years of development,” said Todd May, SLS program manager.

“Our partnership with Orbital ATK and more than 500 suppliers across the country is keeping us on the path to building the most powerful rocket in the world.”

The QM-1 booster weighs in at 1.6 million pounds and required several month of conditioning to heat to the 90 degrees temperature required to conduct the static fire test and thereby qualify the booster design for high temperature launch conditions. It was mounted horizontally in the test stand and measured 154 feet in length and 12 feet in diameter and weighs 801 tons.

Temperatures inside the booster exceeded over 5,600 degrees F.

The static fire test was exquisitely planned to collect data on 103 design objectives as measured through more than 534 instrumentation channels on the booster as it was firing.

The second booster test in March 2016 will be conducted to qualify the propellant temperature range at the lower end of the launch conditions at 40 degrees F.

The first stage of the SLS will be powered by a pair of the five-segment boosters and four RS-25 engines that will generate a combined 8.4 million pounds of liftoff thrust.

The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.
The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.

World’s Most Powerful Solid Booster Set for Space Launch System Test Firing on March 11

All systems are go for the inaugural ground test firing on March 11 of the world’s most powerful solid rocket booster ever built that will one day power NASA’s mammoth new Space Launch System (SLS) heavy lift rocket and propel astronauts to deep space destinations.

The booster known as qualification motor, QM-1, is the largest solid rocket motor ever built and will be ignited on March 11 for a full duration static fire test by prime contractor Orbital ATK at the newly merged firms test facility in Promontory, Utah.

Ignition of the horizontally mounted motor is planned for 11:30 a.m. EDT (9:30 a.m. MDT) on Wednesday, March 11 on the T-97 test stand.

The test will be broadcast live on NASA TV.

A second test is planned a year from now and will qualify the boosters for use with the SLS.

Teams of engineers, operators, inspectors and program managers across Orbital ATK’s Flight Systems Group have spent months getting ready for the QM-1 test. To prepare they started countdown tests on Feb 25.

“The crew officially starts daily countdown test runs of the systems this week, at T-15 days,” said Kevin Rees, director, Test & Research Operations at Orbital ATK.

“These checks, along with other test stand calibrations, will verify all systems are ready for the static test. Our team is prepared and we are proud to play such a significant role on this program.”

NASA’s Magnetospheric Multiscale (MMS) Spacecraft Set for March Blastoff to study Earth’s Magnetic Reconnection Events

NASA’s first mission dedicated to study the process in nature known as magnetic reconnection undergoing final preparation for launch from Cape Canaveral, Florida in just under two weeks time.

The Magnetospheric Multiscale (MMS) mission is comprised of a quartet of identically instrumented observatories aimed at providing the first three-dimensional views of a fundamental process in nature known as magnetic reconnection.

Magnetic reconnection is the process whereby magnetic fields around Earth connect and disconnect while explosively releasing vast amounts of energy. It occurs throughout the universe.

“Magnetic reconnection is one of the most important drivers of space weather events,” said Jeff Newmark, interim director of the Heliophysics Division at NASA Headquarters in Washington.

“Eruptive solar flares, coronal mass ejections, and geomagnetic storms all involve the release, through reconnection, of energy stored in magnetic fields. Space weather events can affect modern technological systems such as communications networks, GPS navigation, and electrical power grids.”

The four MMS have been stacked on top of one another like pancakes, encapsulated in the payload fairing, transported to the launch pad, hoisted and mated to the top of the 195-foot-tall rocket.

The nighttime launch of MMS on a United Launch Alliance Atlas V rocket should put on a spectacular sky show for local spectators along the Florida space coast as well as more distant located arcing out in all directions.

Liftoff is slated for 10:44 p.m. EDT Thursday March 12 from Space Launch Complex 41 on Cape Canaveral Air Force Station, Florida.

The launch window extends for 30 minutes.

After a six month check out phase the probes will start science operation in September.

Unlike previous missions to observe the evidence of magnetic reconnection events, MMS will have sufficient resolution to measure the characteristics of ongoing reconnection events as they occur.

The four probes were built in-house by NASA at the agency’s Goddard Space Flight Center in Greenbelt, Maryland where is visited them during an inspection tour by NASA Administrator Charles Bolden.

I asked Bolden to explain the goals of MMS during a one-on-one interview.

“MMS will help us study the phenomena known as magnetic reconnection and help us understand how energy from the sun – magnetic and otherwise – affects our own life here on Earth,” Bolden told Universe Today.

“MMS will study what effects that process … and how the magnetosphere protects Earth.”

MMS measurements should lead to significant improvements in models for yielding better predictions of space weather and thereby the resulting impacts for life here on Earth as well as for humans aboard the ISS and robotic satellite explorers in orbit and the heavens beyond.

NASA Administrator Charles Bolden poses with the agency’s Magnetospheric Multiscale (MMS) spacecraft, mission personnel, Goddard Center Director Chris Scolese and NASA Associate Administrator John Grunsfeld, during visit to the cleanroom at NASA's Goddard Space Flight Center in Greenbelt, Md., on May 12, 2014.

The best place to study magnetic reconnection is ‘in situ’ in Earth’s magnetosphere. This will lead to better predictions of space weather phenomena.

“This is the perfect time for this mission,” said Jim Burch, principal investigator of the MMS instrument suite science team at Southwest Research Institute (SwRI) in San Antonio, Texas.

“MMS is a crucial next step in advancing the science of magnetic reconnection. Studying magnetic reconnection near Earth will unlock the ability to understand how this process works throughout the entire universe.”

Magnetic reconnection is also believed to help trigger the spectacular aurora known as the Northern or Southern lights.

MMS is a Solar Terrestrial Probes Program, or STP, mission within NASA’s Heliophysics Division.

Watch for Ken’s ongoing MMS coverage and he’ll be onsite at the Kennedy Space Center in the days leading up to the launch on March 12.

Orbital ATK Aims for March 2016 Antares Rocket Launch Restart with New Engines

Orbital Sciences Corporation Antares rocket and Cygnus spacecraft blasts off on July 13 2014 from Launch Pad 0A at NASA Wallops Flight Facility , VA, on the Orb-2 mission and loaded with over 3000 pounds of science experiments and supplies for the crew aboard the International Space Station. Credit: Ken Kremer - kenkremer.com

The newly merged company Orbital ATK is aiming to restart launches of their “upgraded Antares” rocket in March 2016 using completely new engines, following the catastrophic explosion on Oct. 28, 2014 that destroyed the rocket seconds after blastoff from a Virginia launch pad. Antares was carrying a Cygnus module loaded with supplies on a critical space station resupply mission for NASA.

The March 2016 launch date of Antares from the Wallops Island base along Virginia’s eastern shore was announced by David Thompson, Orbital ATK, President and CEO, during a recent conference call with investors and analysts regarding the formal merger of Orbital Sciences and ATK.

“The target date for that [Antares launch] is the 1st of March next year,” said Thompson.

Cygnus will be fully loaded with new supplies for the station crew.

“The first launch … will have a full cargo load on board.”

The Orbital Sciences Corp. commercial Antares rocket was destroyed in a raging inferno about 15 seconds after liftoff on Oct. 28 when one of the Soviet-era built first stage engines apparently exploded and cascaded into a spectacular aerial fireball just above the launch pad 0A at NASA’s Wallops Flight Facility on the doomed Orb-3 mission carrying the Cygnus resupply module to the International Space Station (ISS).

Orbital’s privately developed Cygnus pressurized cargo freighter was loaded with nearly 5000 pounds (2200 kg) of science experiments, research instruments, crew provisions, spare parts, spacewalk and computer equipment and gear on the Orb-3 mission. The module and all its contents were destroyed.

Orbital established an independent accident investigation review board immediately following the launch failure.

“We are about four months now into the recovery from the failure,’ said Thompson.

A turbopump failure in one of the rockets Soviet-era first stage engines has been identified as the most likely cause of the Antares destruction, according to official statements from David Thompson.

The AJ26 engines were originally manufactured some 40 years ago in the then Soviet Union as the NK-33. They were refurbished and “Americanized” by Aerojet Rocketdyne.

“The next Cygnus will be launched on the upgraded Antares from Wallops Island. The target date for that is the 1st of March next year.”

After the launch failure Orbital, decided to ditch the trouble plagued AJ-26 and “re-engineered” the vehicle with new engines.

The Antares first stage had been powered by a pair of the aging AJ26 engines. These will now be replaced by a pair of newly manufactured Russian RD-181 engines, assembled and purchased from NPO Energomash.

“The first launch of the re-engineered vehicle in March of next year … will have a full cargo load on board.”

Thompson said the March 2016 launch target date will be preceded by a hot fire test of the first stage engines, which is currently planned to take place in January 2015. They will not conduct a demonstration launch and have opted for a full up space station resupply flight.

“We’re going to go with the cargo load on the first launch. What we are going to do in advance of that, in January of next year, is we’re going to take the first stage of Antares out to the launch pad with the new engines and do a flight readiness firing, somewhat similar to what we did back in early 2013, in advance of the first Antares flight,” said Thompson.

“But other than that, unless something came up there that was surprising, we should then be able to proceed pretty expeditiously to the first launch of the re-engineered vehicle in March of next year, and that will have a full cargo load on board.”

Thompson also reiterated that Orbital will fully meet its resupply services contarct with NASA and make up for the lost cargo.

The Orbital-3, or Orb-3, mission that ended in disaster on Oct 28, was to be the third of eight cargo resupply missions to the ISS through 2016 under the NASA Commercial Resupply Services (CRS) contract award valued at $1.9 Billion. Under the CRS program Orbital is to deliver 20,000 kilograms of research experiments, crew provisions, spare parts, and hardware for the eight ISS flights.

“The focus all along has been to do everything we can to fulfill our commitments to delivering cargo to the space station for NASA, and to minimize any disruption that we can to the delivery schedules.”

Towards that end Orbital ATK has contracted with United Launch Alliance (ULA) to launch at least one and up to two Cygnus cargo missions to the International Space Station (ISS) under NASA’s Commercial Resupply Services (CRS) program.

The first Cygnus mission would liftoff sometime late in the fourth quarter of 2015 aboard an Atlas V 401 vehicle from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida.

I watched the unfolding disaster first hand from the media viewing site about 1.8 miles away and filed eyewitness reports at the time. Several of my launch pad remote cameras were set up at the pad. They were impounded and the images were used by investigators during the initial investigation. They were returned to me about a month later and are featured here and in my earlier Antares reports.

Watch here for Ken’s ongoing reporting about Antares and NASA Wallops.

25 Years Since Voyager’s ‘Pale Blue Dot’ Images

These six narrow-angle color images were made from the first ever "portrait" of the solar system taken by Voyager 1 on Valentine’s Day on Feb. 14, 1990, which was more than 4 billion miles from Earth and about 32 degrees above the ecliptic.

A quarter of a century has passed since NASA’s Voyager 1 spacecraft snapped the iconic image of Earth known as the “Pale Blue Dot” that shows all of humanity as merely a tiny point of light.

The outward bound Voyager 1 space probe took the ‘pale blue dot’ image of Earth 25 years ago on Valentine’s Day, on Feb. 14, 1990 when it looked back from its unique perch beyond the orbit of Neptune to capture the first ever “portrait” of the solar system from its outer realms.

Voyager 1 was 4 billion miles from Earth, 40 astronomical units (AU) from the sun and about 32 degrees above the ecliptic at that moment.

The idea for the images came from the world famous astronomer Carl Sagan, who was a member of the Voyager imaging team at the time.

He head the idea of pointing the spacecraft back toward its home for a last look as a way to inspire humanity. And to do so before the imaging system was shut down permanently thereafter to repurpose the computer controlling it, save on energy consumption and extend the probes lifetime, because it was so far away from any celestial objects.

Sagan later published a well known and regarded book in 1994 titled “Pale Blue Dot,” that refers to the image of Earth in Voyagers series.

“Twenty-five years ago, Voyager 1 looked back toward Earth and saw a ‘pale blue dot,’ ” an image that continues to inspire wonderment about the spot we call home,” said Ed Stone, project scientist for the Voyager mission, based at the California Institute of Technology, Pasadena, in a statement.

Six of the Solar System’s nine known planets at the time were imaged, including Venus, Earth, Jupiter, and Saturn, Uranus, Neptune. The other three didn’t make it in. Mercury was too close to the sun, Mars had too little sunlight and little Pluto was too dim.

Voyager snapped a series of images with its wide angle and narrow angle cameras. Altogether 60 images from the wide angle camera were compiled into the first “solar system mosaic.”

Voyager 1 was launched in 1977 from Cape Canaveral Air Force Station in Florida as part of a twin probe series with Voyager 2. They successfully conducted up close flyby observations of the gas giant outer planets including Jupiter, Saturn, Uranus and Neptune in the 1970s and 1980s.

Both probes still operate today as part of the Voyager Interstellar Mission.

“After taking these images in 1990, we began our interstellar mission. We had no idea how long the spacecraft would last,” Stone said.

Hurtling along at a distance of 130 astronomical units from the sun, Voyager 1 is the farthest human-made object from Earth.

Voyager 1 still operates today as the first human made instrument to reach interstellar space and continues to forge new frontiers outwards to the unexplored cosmos where no human or robotic emissary as gone before.

Here’s what Sagan wrote in his “Pale Blue Dot” book:

“That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. … There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world.”

Why Can’t We Design the Perfect Spacesuit?

So far, every spacesuit humans have utilized has been designed with a specific mission and purpose in mind. As of yet, there’s been no universal or “perfect” spacesuit that would fit every need. For example, the US ACES “pumpkin” suits and the Russian Sokol are only for launch and reentry and can’t be used for spacewalks. And the Apollo A7L suits were designed with hard soled boots for astronauts to walk on the Moon, while the current NASA EMU and the Russian Orlan are designed for use in space, but with soft soled booties so as not to damage the exterior of the space station.

What would constitute the perfect spacesuit that could be used for any mission? It would have to be lightweight while being impervious to rips, impacts and radiation, but also be flexible, fit multiple sizes, and be comfortable enough to be worn for long periods of time.

With those specifications in mind, is it possible to create the perfect spacesuit?

“Designing a spacesuit turns into a battle between protection and mobility,” said NASA astronaut trainer Robert Frost in an article on Quora. “The more we try to protect the wearer, the less mobile they become. The more mobile we make them, the less protected they are.”

The perfect spacesuit would be, to quote Elon Musk, “badass.”

That’s the terminology the SpaceX used in negotiations with suit-making companies to create the pressure suit for SpaceX’s future commercial passengers. SpaceX is now designing their own suit, and Musk said SpaceX is looking for not just utility but esthetics, too.

“It needs to both look like a 21st-century space suit and work well,” he said during a reddit AMA.

But even with SpaceX’s ‘badass’ suit, they are designing with one purpose in mind.

And there are obstacles to having a “badass space suit design,” wrote Eric Sofge in an article in Popular Science. “A launch-entry suit is ungainly, an oversize one-piece embedded with rigid interfaces for the helmet and gloves, and enough room to inflate, basketball-like, when pressurized—especially in the seat, so an astronaut isn’t forced to stand up.”

New Ideas

One of the best hopes on the horizon is a “shrink-wrap” type of spacesuit that MIT has been developing. It is a lightweight, form-fitting, flexible spacesuit — a la Seven of Nine on Star Trek: Voyager— lined with tiny, muscle like coils.

“With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space,” said one of the developers, Dava Newman. “We want to achieve that same pressurization, but through mechanical counterpressure — applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials. … Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration.”

MIT is using a nickel-titanium shape-memory alloy and they are continuing to test ideas. Some problems with this suit include the difficulty of putting on such a tight suit in a zero-gravity environment and how a gas-pressurized helmet can be connected to the compression-pressurized suit.

NASA recently revealed the winner of a public-voted spacesuit design called the Z-2. While it looks a bit like Buzz Lightyear’s fictional suit, it has bearings in the joints that make more flexible than NASA’s current EMU. It also has a rear-entry port, allowing it to be docked to the side of a mobile transporter or habitat, essentially turning the suit into its own air lock. This helps to avoid bringing in abrasive soil and dust such as lunar regolith Martian soil. NASA is currently testing the Z-2 prototype with plans to develop a better suit, the Z-3. If it works well, the Z-3 might be used in a space walk from the International Space Station by 2017.

So, still, the perfect spacesuit eludes us.

But here are some other additions that would make the perfect spacesuit:

Self-healing: Currently, having multiple layers is the best way to defend against rips or tears, which can be fatal in the vacuum of space. But MIT’s body suit would utilize mechanical counterpressure to counteract a rip, and engineers at ILC Dover are looking into integrating self-healing materials, such as polymers embedded with microencapsulated chemicals that would create a foam to heal a torn suit.

Better gloves: gloves have been one of the hardest things to design in spacesuits. Making a glove that is both flexible and protective is a challenge. Astronaut Duane Carey compared spacewalks to trying to fix your car while wearing winter mittens. Astronauts have had skin rubbed until it bleeds and have lost fingernails because of how the current gloves wear. NASA is constantly working on better gloves.

Augmented Vision: Currently, NASA’s polycarbonate helmets could be confused with fishbowls. One material that could be used for future helmets is a clear ceramic called ALON, which is thinner than bulletproof glass and three times as strong. Another addition could be an internal heads-up display — like ones used by F-16 pilots – to provide data and information.

A better cooling system: Current suits have “underwear” with about 300 feet of plastic tubing that circulate waters to draw away body heat. Purdue University engineers are developing a polymer using glass fibers coated with thermoelectric nanocrystals that absorb heat and discharge electricity.

Artificial Gravity: Remember the magnetic boots worn in Star Trek: The Undiscovered Country and Star Trek: Insurrection? The University of Massachusetts is developing a dry adhesive that could help astronauts and those pesky floating tools to “stick” to surfaces. It is made of a carbon fiber weave and mimics the skin and tendon structure of gecko feet. Another idea — while not quite the same – is a way to counter muscle and bone atrophy in zero-G: Draper Labs are developing gyroscopes the could be attached to the arms and legs of spacesuits that could provide resistance similar to the force of gravity on Earth.

Long-life Battery Power: One issue for long spacewalks is having enough battery power. Michigan Tech is developing units that can convert movement into electricity. Also, Elon Musk might have some ideas for long-lasting batteries…

So, while many entities are working on ideas and concepts, the perfect spacesuit has yet to be developed. If humans are going to go to an asteroid, back to the Moon, to Mars or on a mission to deep space, we’ll need a suit as close to perfect as possible.

The Number of Asteroids We Could Visit and Explore Has Just Doubled

There’s a famous line from Shakespeare’s Hamlet that says “There are more things in heaven and Earth, Horatio, than are dreamt of in your philosophy,” and the same now holds true for brave new worlds for humans to explore.

This result was published earlier this week courtesy of the NASA/JPL Near-Earth Program Office. The study found that the number of possible asteroid targets for human exploration has now doubled from the 666 known in the first study, completed in late 2010.

This information comes from NHATS, which stands for the Near Earth Object Human Spaceflight Accessible Targets Study. Yes, it’s an acronym containing acronyms. NHATS is an automated system based out of Greenbelt, Maryland which monitors and periodically updates its list of potential target candidates for accessibility. The NHATS system data is readily accessible to the public online, and as of February 11^th 2015, 1346 NHATS compliant asteroids are known.

This is the Holy Grail for the future of manned spaceflight, and will represent a good stepping stone (bad pun intended) for future crewed missions to Mars. Several hundred NHATS asteroids require less time and energy to reach than the Red Planet, and a few dozen even require less energy to reach than it does to enter lunar orbit.

Relative delta-V and return velocity is crucial. Apollo astronauts were subject to a blistering 11 kilometre per second reentry velocity on their return from the Moon, and future asteroid missions would be subject to the same style of trajectory on return to Earth from a solar orbit.

The test of the Orion heat shield on reentry during last year’s EFT-1 flight was a step in this direction, and the next test will be an uncrewed launch atop an SLS rocket in September 2018. If all goes according to schedule — and NASA can successfully weather the ever-shifting political winds of multiple future changes of administration — expect to see astronauts exploring an NHATS asteroid placed in lunar orbit sometime around late 2023.

I know. “When I was a kid back in the 70’s…” we expected to be vacationing on Callisto by 2015, as well.

Brent Barbee at NASA’s Goddard Space Flight Center designed the automated NHATS system. It pulls data from a source that many comet and asteroid hunters are familiar with: JPL’s Small Bodies Database. The NHATS system then makes trajectory calculations and patches in conical solutions for possible spacecraft trajectories and actually gives potential launch window dates for future missions. Seriously, its fun to play with… you can even tailor and filter these by target dates versus maximum velocity constraints and the length of stays.

The first discovered NHATS-compliant NEO was 2.3 kilometre 1943 Anteros way back in 1973, and famous alumni on the NHATS list also include 10 metre asteroid 2011 MD, which passed 12,000 kilometres from the Earth on June 27^th, 2011. 2011 MD is on NASA’s short list of asteroids ideal for human exploration. Another famous asteroid on the NHATS list is 99942 Apophis which — triskaidekaphobics take note — will safely miss the Earth by 31,300 kilometres on Friday the 13^th, April 2029. More are added every day, and the growing curve of discoveries also closely mirrors the rise of automated all-sky surveys such as LINEAR, PanSTARRS and the Catalina Sky Survey, though dedicated amateurs do get in on the act occasionally as well.

To date, over 12,000 NEA asteroids are now known, and you can expect future surveys such as the Large Synoptic Survey Telescope set to see first light in 2021 to add to their ranks. The Sentinel space telescope set to launch in 2017 will also boost the known number of NEOs as it covers our sunward blind spot from an orbit interior to the Earth’s. Remember Chelyabinsk? That could actually be a great rallying cry for Sentinel’s cause, as the asteroid came at the Earth from a sunward direction and avoided the sky sweeping robotic eyes of astronomers.

Sometimes, NEOs turn out to be returning space junk from the early Space Age (a low relative velocity and low orbital inclination is often a dead giveaway). Earth has also been known to capture an NEO as an occasional temporary second Moon, as occurred in 2006 in the case of asteroid 2006 RH120.

But beyond just creating a database, the NHATS system also presents key opportunities for astronomers to perform follow-up observations of NEO asteroids, which is vital for precisely characterizing their orbits. Two future missions are also planned to return samples from NHATS asteroids: Hayabusa 2, which launched on December 3^rd 2014 headed for asteroid 1999 JU₃ in July 2018, and the OSIRIS-REx mission, set to launch in late 2016 headed for asteroid 101955 Bennu in 2018.

NHATS is providing a crucial target list for that day when first human footfall on an asteroid occurs… or should we say docking?

All the World’s Rockets, Past, Present and Future

The world's greatest rockets, past, present and future. Credit and copyright: Alex Brown.

MOAR rockets! As a followup to our recent post about the Rockets of the World (to scale), here’s another graphic posted on imgur, created by Alex Brown. While the earlier graphic only included rockets that had flown, this one has rockets that are also in development, such as the SLS, Falcon Heavy and the Long March 9. It’s also a great look back at the history of rocket development, including the V-2 ballistic, England’s Black Arrow and Korolyov’v wide-body Sputnik. All are shown to scale, as compared with an average human being.

As noted, this graphic is as of the present, February 2015.

Flying Sky Car: The Skylon Explainer Inspired by xkcd

Reaction Engine's Skylon spaceplane explained in the '10 hundred words' that people use the most. Credit: celerycoloured on reddit.

Just about everyone can claim to being inspired by the xkcd webcomic — or at least enjoying a shared nerd moment. A favorite comic of many space fans is the Up Goer Five poster, which explains the Saturn V rocket in the “10 hundred” (i.e. 1,000) English words that are used most frequently.

Now, one fan of xkcd, celerycoloured on reddit has created a poster of the single-stage-to-orbit Skylon spaceplane being built by the British company Reaction Engines Limited (REL). With some great hand-drawn graphics, this homage poster uses — again — the most commonly used words in the English language to explain Skylon:

“The first space car that may go to space without parts falling off” describes the single stage to orbit idea, and “this space car can burn the air outside so it doesn’t have to take so much breathing type air or drop parts” explains the air-breathing SABRE engines.

“I’d just like people to know more about REL,” celerycoloured told Universe Today. “Their efforts towards reusable SSTO spacecraft is one of the coolest things I’ve seen!”

Read about Skylon in more complex terms here.

In other space plane news today, ESA’s Intermediate eXperimental Vehicle IXV successfully launched on a Vega rocket from the Kourou space center for a one hour forty minute test flight. This is a lifting body vehicle similar to the X37B, however the IXV splashed down in the ocean for this first flight.
