NASA Avoids Accountant’s Axe

With the US’s attention firmly focused on the budget with calls to cut spending in every possible non-essential programs, supporters of the U.S. human space flight program were concerned that NASA would be on the frontline to take a hit. But Congress spared the space agency from prospective cuts and announced that NASA’s budget would remain at current levels, and its budget be $18.5 billion for 2011. It took the body months of vitriolic back-and-forth arguing that culminated in last-minute negotiations, including language that includes the building of a Space Launch System heavy-lift vehicle.

NASA is at a historic crossroads as the agency has been directed to support smaller commercial space firms provide access to low-Earth-orbit (LEO) while the agency tries to send astronauts beyond LEO again.

The wording of the budget states that the Space Launch System heavy-lift vehicle “shall have a lift capability not less than 130 tons and which shall have an upper stage and other core elements developed simultaneously.” That’s different from the language in the 2010 authorization act, which calls for initial development of an SLS that can place 70-100 tons into LEO that would later be upgraded to a 130-ton capacity.

As it currently stands, NASA is dependent on the Russian Soyuz spacecraft to send U.S. astronauts to the International Space Station. Russia has recently increased the cost of a single seat onboard the Soyuz to $63 million, making it even-more important that NASA maintains funding at least at current levels.

“We appreciate the work of Congress to pass a 2011 spending bill. NASA now has appropriated funds to implement the 2010 Authorization Act, which gives us a clear path forward to continue America’s leadership in human spaceflight, exploration and scientific discovery. Among other things, this bill lifts funding restrictions that limited our flexibility to carry out our shared vision for the future,” said NASA’s Administrator Charles Bolden. “With this funding, we will continue to aggressively develop a new heavy lift rocket, multipurpose crew vehicle and commercial capability to transport our astronauts and their supplies on American-made and launched spacecraft. We are committed to living within our means in these tough fiscal times – and we are committed to carrying out our ambitious new plans for exploration and discovery.”

Lifted, finally, was the so-called “Shelby provision” from the 2010 appropriations act that prevented NASA from terminating Constellation programs.

NASA Space Shuttle Owner’s Workshop Manual Book Review

The shuttle era is ending and when things end people have the tendency to look back and reflect on the trials and tribulations of that period. There are many news books that are being produced that seek to capitalize on this nostalgia – and a few old ones, are being re-released with current and updated information within. One of the more notable efforts is NASA SPACE SHUTTLE Owner’s Workshop Manual.

With modern imagery and text reflective of the program’s long history, the book encapsulates all of the accomplishments that the vehicle’s design allowed to become a reality. The book uses very current information, so much so that it mentions the shooting of U.S. Congresswoman Gabrielle Giffords which took place this past January.

The book provides for a succinct review of the program’s history, its contributions, the setbacks of the Challenger and Columbia disasters as well as other aspects both known and unforeseen of the vehicle’s overall design. Although the book is relatively short, it covers the rationale behind why the space shuttle was designed the way that it was, how the spacecraft launches, flies and lands as well as numerous other facets that comprised the space shuttles’ history.

Written by Dr. David Baker and published by Zenith Press, the book retails for $28 and is well worth the price. With only two flights left before the shuttles are sent to their final resting places in museums and theme parks around the nation this book will make for a great memento of the vehicle that placed the Hubble Space Telescope in orbit, that helped build the International Space Station and that has been the focal point of U.S. human space efforts for the past thirty years.

At Shuttle Program’s Twilight, Tears and Cheers as Triumphs and Tragedies are Remembered

NASA Administrator Charles Bolden gets choked up during the 30th anniversary of the shuttle program.

[/caption]

CAPE CANAVERAL – With the shuttle program’s end less than three months away, NASA took time to honor the program that has been the focal point of the agency’s manned space flight efforts for the past thirty years. At 1 p.m., NASA’s Administrator, Charles Bolden, along with Kennedy Space Center Director Robert Cabana, astronaut Janet Kavandi, shuttle Endeavour’s Vehicle Manager Mike Parrish and STS-1 Pilot Robert Crippen spoke to NASA employees and members of the media regarding the programs long history and its many achievements.

However, the most important announcement of the day was where the remaining shuttles will go when the program draws to a close. It was announced that the space shuttle Enterprise, a test article of the shuttle design, will move from its current home at the Smithsonian’s National Air and Space Museum Steven F. Udvar-Hazy Center in Virginia to the Intrepid Sea, Air & Space Museum in New York. The Udvar-Hazy Center will be home for Discovery, which finished its last mission in March. Endeavour, which is being readied for its final flight at the end of this month, will go to the California Science Center in Los Angeles. Atlantis, which is currently scheduled to fly the last shuttle mission in June, will go to the Kennedy Space Center Visitor Complex in Florida.

Although Bolden and Cabana are former astronauts, they were joined by one of the two men that flew the very first shuttle mission, STS-1 – Robert Crippen. This mission is viewed as one of the most risky test flights in history. If something had gone wrong during the first mission’s launch, Crippen and Commander John Young would have had to eject from Columbia – through the vehicle’s fiery plume. However, everything worked according to plan and Columbia landed at Edwards Air Force Base in California two days later.

The weight of the day’s events had an obvious impact on Bolden and Crippen, both of whom were visibly emotional during the presentation. Crippen’s comments detailed the feelings of many in that this is a bitter-sweet anniversary. Those in attendance supported the four-time shuttle veteran with loud applause when it was announced that Atlantis would remain at Kennedy Space Center.

“Stay focused, “said Bolden during his comments, referring to the gap in manned space flight that is about to take place. “It’s been a rough day.”

There was also a guest appearance from the current members of the International Space Station who called in from on orbit. They apologized for not being able to attend – before they acknowledged it was thanks to the hard work of those present that they couldn’t be there. Astronauts Cady Coleman, Ron Garan were joined by ESA astronaut Paolo Nespoli as well as cosmonauts Dmitry Kondratyev, Andrey Borisenko and Alexander Samokutyaev. The station’s crew spoke about how the shuttle program made this international effort possible.

On April 12, 1981, the space shuttle Columbia roared into orbit on the first mission of the shuttle program. The first crew only had two astronauts on board, Apollo veteran John Young and rookie astronaut Robert Crippen. The first flight of the shuttle program took place 20 years to the day that the first human rode fire into orbit – Yuri Gagarin.

There are currently only two shuttle flights remaining, Endeavour is slated to conduct its 25th and final mission, STS-134, at the end of this month and Atlantis will launch the final mission on June 28. Once this mission is over, NASA will have to rely on Russia for access to the International Space Station until small, commercial firms; those supported under President Obama’s new plans for NASA can produce a launch system to fill the void.

“I would have been happy to get any of the orbiters here at KSC,” said Robert Crippen when interviewed. “Getting Atlantis makes this a very good day.”

NASA Administrator Charles Bolden today unveiled the winners in the bidding war to become home to one of NASA’s retiring space shuttle orbiters. Bolden selected the Kennedy Space Center in Florida, the California Science Center, the Intrepid Sea, Air and Space Museum in New York City, and the Smithsonian National Air and Space Museum, outside Washington D.C.

Bolden made the announcement at a ceremony at the Kennedy Space Center coinciding with the 30th anniversery of the first space shuttle flight. Space Shuttle Columbia blasted off on the STS-1 mission on April 12, 1981. Today is also the 50th anniversary of the first manned spaceflight by Cosmonaut Yuri Gagarin on April12, 1961.

Only two shuttle flights remain before the Space Shuttle Program and the orbiters are retired after 30 years of speceflight and 133 mission so far. The final two missions – STS-134 and STS 135 – are slated for late April and late June 2011.

The orbiters will then be transferred to their new homes and put on display where NASA hopes they will inspire the next generation of explorers and engineers. But the word mentioned by Bolden and all the other speakers was “bittersweet” – because today is a mixture of sadness that the orbiters are being retired while still flight worthy and happiness that the program has achieved so much.

Atlantis, the final shuttle to fly, will be displayed at the Kennedy Space Center Visitor Complex. Kennedy is the natural home to the orbiters and where every shuttle mission has launched and where every shuittle mission is processed for flight.

Kennedy plans to disiplay shuttle Atlantis as though it were “In Flight”. Read my earlier story on Kennedy’s proposal to showcase the orbiter with interactive exhibits and numerous shuttle program artifacts , such as like the White Room and the Beenie Cap.

As expected, Shuttle Discovery was assigned to the Smithsonian’s National Air
and Space Museum Steven F. Udvar-Hazy Center in Virginia. Discovery is the fisrt of the orbiters to be retired and just completed its final mission, STS -133, in March 2011

The prototype orbiter Enterprise, which is currently on display at the Smithsonian, will be moved up the east coast to the Intrepid Sea, Air & Space Museum in New York City

Space Shuttle Endeavour will go to the California Science Center in Los Angeles, near to the location where all the shuttle orbiters were constructed. Endeavour will be the only orbiter to be display outside the east coast. Endeavour is being processed for her final flight, the STS-134 mission, set to launch on April 29.

Oddly left out is the Johnson Space Center, home to all the Space Shuttle astronauts and their training facilities.

Today, April 12, is the 50th Anniversary of Earth’s first manned spaceflight by Hero Cosmonaut , Yuri Gagarin of what was then the Soviet Union. He was strapped aboard the Vostok 1 spacecraft and blasted off to the High Froniter at 9:07 a.m. Moscow time from the Baikonur Cosmodrome

Roskosmos – the Russian Federal Space Agency – honors his memory with this stirring video tribute chronicling the Flight of Yuri Gagarin. The outstanding video is set to the song “Seed” with lyrics sung by the Russian Red Army Choir. Dramatic video clips show rare views of Gagarin in training, the actual launch day events and concludes with his grand reception.

Gagarin’s smile is infectious and the video brings him to life. Watch and enjoy – several times . And be prepared to journey back in time to the era of the Space Race and the Soviet Union.

Included below is another music video with more amazing videos clips from the Flight of Yuri Gagarin on April 12, 1961and a brief video summarizing his all too short life. Gagarin would have been celebrating his 75th birthday on March 9.

Mark your calendars. April 12, 2011 marks the 50th Anniversary of Human Spaceflight and Cosmonaut Yuri Gagarin’s astonishing First Orbit of our precious planet Earth on April 12, 1961. Gagarin was the first human to enter outer space and see what no one else had ever witnessed – our commonly shared Earth as a planet and beautiful blue globe with no borders.

Space enthusiasts worldwide are celebrating this watershed moment in Human history at a network of over 400 “Yuri’s Night” parties taking place in more than 70 countries on 6 continents and 2 worlds, according to the official “Yuri’s Night” website.

Gagarin’s flight took place in the midst of the inflammatory Cold War rivalry between the Soviet Union and the United States and shocked the world into new realities. The Space Race led to the first lunar landing by the United States and Neil Armstrong’s first steps on the moons surface in 1969. Eventually, the world’s superpowers beat swords into plowshares and united their efforts to build the International Space Station.

Yuri Gagarin was the first person to boldly leave the bonds of Earth’s gravity and thus became the first “Spaceman”. Gagarin blasted off inside the bell-shaped Vostok 1 spaceship from the launch pad at Baikonur at 9:07 a.m, Moscow time (607 UTC) to begin the era of human spaceflight.

Gagarin flew around the Earth in a single orbit at an altitude of 302 kilometers (187 miles). The flight lasted 108 minutes and safely ended when he descended back and parachuted to the ground, just north of the Caspian Sea. At the age of 27, Gagarin was instantly transformed into a worldwide hero. After the momentous flight he soon embarked on an international tour.

20 years later on April 12, 1981, NASA’s first space shuttle blasted off on the STS-1 mission on a daring test flight with astronauts John Young and Bob Crippen strapped inside Space Shuttle Columbia.

The first “Yuri’s Night – World Space Party” was held on April 12, 2001 to commemorate the 40th anniversary of Gagarin’s spaceflight. Over 10,000 people attended 64 events located worldwide. The goal was to inspire people, increase awareness and support for space exploration across the globe and foster the spread of new ideas to broaden our access to space.

“Yuri’s Night” has been growing in popularity every year. Events range in size from a few folks to numbers in the thousands. Attendees range from astronauts and cosmonauts, NASA and global space agency officials and reps, scientists and engineers, famous actors, playwrights, writers, artists, athletes and musicians to just everyday folks and kids of all ages and backgrounds. Everyone can get involved.

Yuri Gagarin in orbit
In honor of the 50th anniversary of Gagarin’s flight, documentary film maker Christopher Riley conceived and created a film titled “First Orbit” to try and show the approximate view of Earth that Gagarin actually saw. There is only scant footage of Gagarin’s actual flight and he himself took no pictures of the Earth from orbit.

“First Orbit” recreates much of the view of the Earth’s surface that Gagarin would have seen fifty years ago. Mostly he flew over the world oceans as well as the Soviet Union and Africa.

Riley collaborated with the astronauts aboard the International Space Station, chiefly Paolo Nespoli of ESA, who took film footage from the new 7 windowed Cupola as the station matched the actual flight path of Gagarin and Vostok 1 as closely as possible. The free film celebrates 50 years of human spaceflight.

“First Orbit” premiers worldwide on YouTube in a special global streaming event for Yuri’s Night on April 12 . Watch the short trailer below, with original and stirring music by Philip Sheppard.

It’s easy and free to register your local party at the Yuri’s Night event website. There is still time to register your Yuri’s Night party – Indeed the list has grown as I typed out this story !

Some events are already set to kick off this weekend. I’ll be presenting at an interactive and free Yuri’s Night evening event in Princeton Junction, New Jersey, about Gagarin’s flight and my experiences with the space shuttle and what‘s beyond.

How Would a Government Shutdown Affect NASA?

NASA faces the curtaillment of many jobs and services during a government shutdown including website updates. Image credit: (and with thanks) Heather Archuletta.

The big question weighing on the minds of anyone involved or interested in US space exploration is how a US government shutdown would affect the space agency. In short, if a NASA job or service is curtailed or a department or building is closed and it doesn’t threaten a life, a spacecraft, data, or a mission, it won’t be continued during a government shutdown. That means thousands of NASA employees would be furloughed, scientists for robotic missions won’t be able to work on gathering new data, and the STS-134 launch could be delayed indefinitely until Congress passes a budget.

While the shuttle mission wouldn’t launch as scheduled on April 29 to the International Space Station because of a shutdown, all NASA workers essential to the ISS and its operations would continue to work, as well as those who keep the space shuttle Endeavour – out on the launchpad – safe and stable. Additionally, engineers involved with NASA’s many space probes and Earth orbiting satellites who monitor spacecraft health and keep them functioning – those “necessary to prevent harm to life or property” as NASA put it, would keep working. But scientists and researchers involved with those missions will likely be sent home.

In a letter to the Office of Management and Budget, NASA Chief Financial Officer Elizabeth Robinson provided an update on how NASA will function in the event of a government funding hiatus. “The decision on what personnel should be excepted from furlough is very fact specific, and Directors in charge of NASA Centers are in the best position to make detailed decisions regarding the suspension of ongoing, regular functions which could imminently threaten the safety of human life or the protection of property,” Robinson wrote.

For example, at NASA Headquarters, there are 1,611 total employees, and only 22 are considered “essential” and would not be furloughed. At NASA’s Ames Research Center, only 25 out of 1250 full time employees would not be furloughed if and when shutdown happens.

A government employee told us that during a furlough, even if someone is classified as “essential” or “exempted” and has to come in and work, they won’t get paid until later. For “non-essential” employees, there is no guarantee the government will provide any compensation for the time the government offices are is closed. “For the shutdown in 1995, they DID give everyone back pay,” said the employee, who wished to remain anonymous. “But this time? Who knows?”

For anyone who lives and breathes NASA on the internet, you will find your lifeblood cut. NASA TV will not broadcast. NASA websites will not be updated including the main nasa.gov site; the NASA Earth Observatory website sent out an email to notify subscribers that they will not be able to update starting April 9 if the shutdown occurs. This is for security reasons, since IT people won’t be there to maintain and secure the websites.

NASA employees, including astronauts who have “official” Twitter accounts have been ordered not to Tweet under a government shutdown and the same goes for Facebook updates for any official NASA account or mission. One exception is that ESA astronaut Paolo Nespoli on board the ISS can still use Twitter.

Any tours and public access to NASA Centers and facilities will be canceled, and any NASA instructors at schools or universities will be ordered not to report. A news conference scheduled for April 12 at the Kennedy Space Center to announce which museums will have won the rights to display NASA’s three space shuttles would has been put on hold pending the government shutdown.

These and other things will occur if no agreement is reached on a fiscal year 2011 budget by midnight tonight, (Friday, April 8, 2011). For more details, see this NASA page which includes three pdf documents which outline what happens for the space agency during a government shutdown. Without getting into the politics, the entire situation is very sad and disheartening.

Spring Fireballs

For reasons yet unknown, the rate of midnight fireballs increases during the weeks around the vernal equinox. It’s a beautiful display, but where do they come from? Last month, we reported on a network of fireball cameras that NASA is building, which is now tracking incoming fireballs — and just in time, too, for the fireball season. This video is part of a new series by NASA called ScienceCast, which will be a weekly feature highlighting a topic in NASA science news.

Curiosity Mars Rover Almost Complete

NASA’s massive ‘Curiosity’ rover is almost ready to begin the first leg of its long trek to the surface of the Red Planet. Engineers at NASA’s Jet Propulsion Laboratory in California are nearly finished with assembling and testing all the components of the Mars Science Laboratory (MSL) mission (see photos above and below).

The MSL team plans to ship Curiosity as well as the cruise stage, descent stage and back shell to the Kennedy Space Center (KSC) in May and June. After arriving at KSC, all the pieces will be integrated together and tested during final assembly in a clean room. The rover will then be installed inside a 5 meter diameter nose cone, shipped the short distance to Cape Canaveral and then bolted atop an Atlas V rocket (photo below).

The launch window for Curiosity extends from Nov. 25 to Dec. 18, 2011. The first stage of the powerful Atlas V rocket will be augmented with four solid rocket boosters. The Atlas V has previously launched two planetary missions; the Mars Reconnaissance Orbiter (MRO) and the New Horizons mission to Pluto.

Take a long gander at the 3 meter long rover because its appearance is now very much how it will look while it’s roving along intriguing martian landscapes for at least two earth years after landing in August 2012.

The mini-Cooper sized Curiosity rover is equipped with 10 science instruments to investigate Martian soil and rock samples in far greater detail than ever before. Curiosity’s science payload weighs ten times more than any prior Mars rover mission.

The goal is to search for clues to environmental conditions favorable for microbial life and for preserving evidence about whether Martian life ever existed in the past or today. NASA is scrutinizing a list of four potential landing sites for the best chance of finding a habitable zone.
