NASA is Going to Add a Commercial Module to the Space Station

NASA’s plan to open up the International Space Station (ISS) to commercial activity is gaining ground. They have a vision for an economy in Low-Earth Orbit (LEO) called the Plan for Commercial LEO Development. According to NASA, they intend to foster economic development in LEO and to drive innovation, all for the benefit of the American economy.

Now they’ve selected Axiom Space of Houston to provide a commercial habitation module for the ISS.

Here’s What the Climate Might Look Like on Proxima Centauri B

Located at the heart of the NASA Center for Climate Simulation (NCCS) – part of NASA’s Goddard Space Flight Center – is the Discover supercomputer, a 129,000-core cluster of Linux-based processors. This supercomputer, which is capable of conducting 6.8 petaflops (6.8 trillion) operations per second, is tasked with running sophisticated climate models to predict what Earth’s climate will look like in the future.

However, the NCCS has also started to dedicate some of Discover’s supercomputing power to predict what conditions might be like on any of the over 4,000 planets that have been discovered beyond our Solar System. Not only have these simulations shown that many of these planets could be habitable, they are further evidence that our very notions of “habitability” could use a rethink.

A Cubesat Deployed a De-Orbiting Tether and Now it’s Losing Altitude 24 Times Faster than Before

A company called Tethers Unlimited has deployed its de-orbiting tether in a successful test on the Prox-1 satellite. The satellite is one of four that are carrying the device, called the Terminator Tape. Rather than stay in space for years or decades, and add to the growing problem of space debris, Prox-1 is using its Terminator Tape to slowly lower its orbit.

A Television Satellite Might be About to Explode

On Friday (Jan. 19th), authorities at the Federal Communications Commission (FCC) announced that they had granted permission to cable tv provider DirecTV to begin the process of deorbiting their Spaceway-1 (F1) satellite. This was necessary ever since DirecTV detected a “major anomaly” with the satellite’s batteries which increased the risk of an explosion if its orbit remained unchanged.

The Brightest Supernova Ever Seen was Caused by a White Dwarf Spiraling into a Red Giant

Super-luminous supernovae are the brightest explosions in the Universe. In just a few months, a super-luminous supernova can release as much energy as our Sun will in its entire lifespan. And at its peak, it can be as bright as an entire galaxy.

One of the most-studied super-luminous supernovae (SLSN) is called SN 2006gy. Its origin is uncertain, but now Swedish and Japanese researchers say they might have figured out what caused it: a cataclysmic interaction between a white dwarf and its massive partner.

ESA is Going to Test Two Rovers Working Together to Explore the Moon

The ESA has spent the past few years working towards the creation of an international lunar base, something that will serve as a spiritual successor to the International Space Station (ISS). To accomplish this, they have enlisted the help of other space agencies and contractors to develop concepts for space habitats and construction methods as well as ways to provide robotic and logistical support.

Recently, the ESA’s Technology Development Element (TDE) signed on with the French technology developer COMEX to create the TRAILER robotic system. This two-year project will test a new mission architecture where two rovers work in tandem (and with the help of astronauts) for the sake of exploring the lunar surface and building a permanent outpost on the Moon.

The Apollo 1 Fire: Excerpt from “Eight Years to the Moon”

The Apollo 1 prime crewmembers for the first manned Apollo Mission prepare to enter their spacecraft inside the altitude chamber at the Kennedy Space Center (KSC) in 1966. Entering the hatch is astronaut Virgil I. Grissom, commander; behind him is astronaut Roger B. Chaffee, lunar module pilot; standing at the left with chamber technicians is astronaut Edward H. White II, command module pilot. Credit: NASA

Editor’s note: Today marks the 53rd anniversary of the Apollo 1 fire that killed three astronauts during a routine test on the launchpad. The test was a dress rehearsal for the Apollo 1 crew — Gus Grissom, Ed White and Roger Chaffee. The goal was to check out the command module, NASA’s first spacecraft that would take astronauts to the Moon.

Following is an excerpt about the fire from the book “Eight Years to the Moon: The History of the Apollo Missions” by Nancy Atkinson. The book tells the unique personal stories of over 60 engineers and scientists who worked behind the scenes to make the Apollo program possible, and is filled with stories of the dedication and perseverance it took to overcome the challenges, hurdles and conflicts of doing things that had never been done before. It provides a glimpse into the lives of some of the hundreds of thousands of people who made it possible to land humans on the Moon. While many of the stories in the book are fun and heart-warming, this excerpt shares the incredibly heart-breaking event that shocked the country and halted the Apollo program as NASA scrambled to figure out what went wrong.
