The ExoMars Rover is Ready, now it Just Needs a new Ride to Mars

When it arrives on Mars, the ESA’s Rosalind Franklin rover will join a growing fleet of robotic rovers, landers, and orbiters dedicated to searching for life on Mars. As part of the Exomars program, this mission was a collaborative effort between the ESA and the Russian State Space Corporation (Roscosmos). Whereas the ESA would provide the rover, Roscosmos was to provide the launch services and the Kazachok lander that would deliver Rosalind Franklin to the surface.

After many years of development, testing, and some delays, the Rosalind Franklin rover passed its System Qualification and Flight Acceptance Review in March. The Review Board confirmed that the rover was ready to be shipped to the launch site at Baikonur Cosmodrome and would make the launch window opening on September 20th, 2022. Unfortunately, due to the suspension of cooperation with Roscosmos, the ESA’s rover finds itself stranded on Earth for the time being.

NASA Will be Testing SLS Over the Weekend

The Space Launch System (SLS) has just one more hurdle to clear before this summer’s historic launch. This is known as the Wet Dress Rehearsal, where the fully-stacked SLS and Orion spacecraft will conduct a series of operations at the NASA Kennedy Space Center in Florida. This test follows the arrival of the SLS to Launch Complex 39B after making its big rollout on March 17th from the Vehicle Assembly Building (VLB).

The Wet Dress Rehearsal will run from Friday, April 1st, through Sunday, April 3rd, and will see the Artemis I launch team load propellant into the rocket’s tanks, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and also drain propellants to give them an opportunity to practice the timelines and procedures they will use for launch. The weekend-long event will be live-streamed via the Kennedy Newsroom YouTube channel.

New Simulation Recreates an Early Time in the Universe That Still Hasn't Been Seen Directly

The fields of astronomy and astrophysics are poised for a revolution in the coming years. Thanks to next-generation observatories like the James Webb Space Telescope (JWST), scientists will finally be able to witness the formation of the first stars and galaxies in the Universe. In effect, they will be able to pierce the veil of the Cosmic Dark Ages, which lasted from roughly 370,000 years to 1 billion years after the Big Bang.

During this period, the Universe was filled with clouds of neutral hydrogen and decoupled photons that were not visible to astronomers. In anticipation of what astronomers will see, researchers from the Harvard & Smithsonian Center for Astrophysics (CfA), the Massachusetts Institute of Technology (MIT), and the Max Planck Institute for Astrophysics (MPIA) created a new simulation suite called Thesan that simulates the earliest period of galaxy formation.

ESA’s Solar Orbiter Takes a Ludicrously High Resolution Image of the Sun

The European Space Agency’s Solar Orbiter snaps an amazing image, en route to its first close pass near the Sun.

You’ve never seen the Sun like this. Earlier this month, the European Space Agency’s Solar Orbiter captured an amazing view of our host star.

The images were snapped on March 7^th, as Solar Orbiter passed directly between the Earth and the Sun. There was an explicit reason for this, as the science team wanted to calibrate and compare the images with Earth-based and missions in Earth orbit, to include the Inouye solar observatory, NASA’s Solar Dynamics Observatory and the joint ESA/NASA Solar Heliospheric Observatory (SOHO), located at the Lagrange (L1) Sun-Earth point.

Starship Could be Ready for an Orbital Flight in May

SpaceX has enjoyed a lot of wins in the past few years. In addition to successfully glide-testing and landing multiple Starship prototypes, they’ve rolled out its first Super Heavy boosters, test-fired the new Raptor Vacuum engines, and assembled the “Mechazilla” launch tower at Boca Chica, Texas. They also unveiled the first fully-furbished orbital test vehicle (SN20) that was stacked with a first stage booster for the first time on its launch pad.

Given the prodigious rate of progress, few were surprised when Musk announced that the first orbital flight test could take place as soon as January 2022. Unfortunately, this date had to be pushed back to an environmental assessment and the usual bureaucratic rigmarole. However, Musk recently announced on Twitter that in light of his company’s success with the new Raptor engines, they could be ready to conduct the long-awaited orbital test flight this May.

Three Cosmonauts Arrive at the ISS Wearing Bright Yellow Jumpsuits

About a month ago, Russian forces invaded Ukraine, placing NATO on high alert and creating a shock wave felt around the world. One place that has been particularly resilient to the effects of this conflict is the International Space Station (ISS). Even as tensions mount and the heads of space agencies engage in an online war of words, astronauts and cosmonauts continue to work and live together in orbit.

On the other hand, there have been some clear attempts to drag the ISS into political turmoil. Case in point: the recent photo that shows three Russian cosmonauts wearing bright yellow and blue jumpsuits, the colors of the Ukrainian flag! Depending on who you ask, this was either a display of unity with the people of Ukraine or just a coincidence. Opinions vary, but this was likely nothing more than oddly fortuitous.

U.S. Space Force CHPS to Patrol Around the Moon

An innovative new network CHPS may control space traffic around the Moon.

As human activity extends outward into the solar system, we’ll need a way to keep track of space junk, and the growing number of missions around the Moon and beyond.

Recently, the newly-formed U.S. Space Force announced plans to create CHPS, the Cis-lunar Highway Patrol System. Despite an acronym harking back to a certain cheesy TV series in the 1970s, CHPS will provide a serious look at space traffic further out in orbit around the Earth-Moon system. Such a network is vital, as private companies and space agencies are set to return to the Moon in a big way in the coming decade.

Wondering how Dependant ISS is on Russia? NASA Gives the Details

The Russian invasion of Ukraine has been dominating the news cycle lately. Amid tragic stories about rocket strikes, stalled offensives, and possible motives and outcomes, there’s been an ongoing “war of words” on social media. In particular, Dmitry Rogozin, the Director-General of the Russian State Space Corporation (Roscosmos), has been issuing thinly-veiled threats that Russia might be terminating its cooperation in space.

This included a video posted on Telegram by the state-controlled Russian news agency RIA Novosti that shows the Russian modules detaching from the International Space Station (ISS). In response to all the threats and hyperbole, NASA decided to host an FAQ session where they posted commonly-asked questions about the ISS. In what is eerily reminiscent of what happened in 2014, NASA let the world know that the ISS is still going strong and won’t be decommissioned anytime soon!

Pearl Jam's Eddie Vedder Provides the Music for NASA's new SLS Video

For fans of Eddie Vedder, Pearl Jam, and space exploration, this video will require very little explanation. But just in case some people haven’t seen it yet, this musical performance was a tribute to the long-awaited roll-out of the fully-stacked Space Launch System (SLS) at the NASA Kennedy Space Center in Florida. It’s guaranteed to give you goosebumps and maybe even bring a tear to your eye!

Why Would an Alien Civilization Send Out Von Neumann Probes? Lots of Reasons, says a new Study

In 1948-49, mathematician, physicist, computer scientist, and engineer John von Neumann introduced the world to his idea of “Universal Assemblers,” a species of self-replicating robots. Von Neumann’s ideas and notes were later compiled in a book titled “Theory of self-reproducing automata,” published in 1966 (after his death). In time, this theory would have implications for the Search for Extraterrestrial Intelligence (SETI), with theorists stating that advanced intelligence must have deployed such probes already.

The reasons and technical challenges of taking the self-replicating probe route are explored in a recent paper by Gregory L. Matloff, an associate professor at the New York City College of Technology (NYCCT). In addition to exploring why an advanced species would opt to explore the galaxy using Von Neumann probes (which could include us someday), he explored possible methods for interstellar travel, strategies for exploration, and where these probes might be found.
