As part of their Commercial Crew Development (CCDev) Program, NASA has contracted with aerospace giants like SpaceX and Boeing to provide commercial launch services to the International Space Station (ISS). These services will consist of SpaceX’s Crew Dragon (Dragon 2) and Boeing’s CST-100 Starliner bringing astronauts to orbit in the coming years, effectively restoring domestic launch capability to the US.
To get these spacecraft ready for flight, Boeing and SpaceX have been putting them through rigorous launch tests. Tomorrow morning (Saturday, Jan. 17th), SpaceX will be conducting its final test in preparation for crewed flights. This is the all-important in-flight abort test, which will be live-streamed by NASA TV – will take place at 7:45 AM EST (4:45 AM PST) from Launch Complex 39A in Florida.

In 2012, the balloon-borne observatory known as the Super Trans-Iron Galactic Element Recorder (SuperTIGER) took to the skies to conduct high-altitude observations of Galactic Cosmic Rays (GCRs). Carrying on in the tradition of its predecessor (TIGER), SuperTiger set a new record after completing a 55-day flight over Antarctica – which happened between December of 2012 and January of 2013.
On December 16th, 2019, after multiple launch attempts, the observatory took to the air again and passed over Antarctica twice in the space of just three and a half weeks. Like its predecessor, SuperTIGER is a collaborative effort designed to study cosmic rays – high-energy protons and atomic nuclei – that originate outside of our Solar System and travel through space at close to the speed of light.

When it takes to space in 2025, the Wide-Field Infrared Survey Telescope (WFIRST) will be the most powerful observatory ever deployed, succeeding the venerable Hubble and Spitzer space telescopes. Relying on a unique combination of high resolution with a wide field of view, WFIRST will be able to capture the equivalent of 100 Hubble-quality images with a single shot and survey the night sky with 1,000 times the speed.
In preparation for this momentous event, astronomers at NASA’s Goddard Space Flight Center have been running simulations to demonstrate what the WFIRST will be able to see so they can plan their observations. To give viewers a preview of what this would look like, NASA’s Goddard Space Flight Center has shared a video that simulates the WFIRST conducting a survey of the neighboring Andromeda Galaxy (M31).

Boeing’s Starliner crew capsule launched successfully, but a mishap prevented it from docking with the ISS. The ship is undamaged and will return and land at its designated location, according to officials. This could delay the planned crewed flight of the Starliner next summer.

NASA’s X-Plane Program has been around for 70 years. Over the course of those decades, the agency has developed a series of airplanes and rockets to test out various technologies and design advances. Now NASA has cleared the newest one, the X-59, for final assembly.

When stars exhaust their supply of fuel, they collapse under their own weight and explode, blowing off their outer layers in an event known as a “supernova”. In some cases, these events leave behind neutron stars, the smallest and densest of stellar objects (with the exception of certain theoretical stars) that sometimes spin rapidly. Pulsars, a class of neutron star, can spin up to several hundred times per second.
One such object, designated J0030+0451 (J0030), is located about 1,100 light-years from Earth in the Pisces constellation. Recently, scientists using NASA’s Neutron star Interior Composition Explorer (NICER) were able to measure the pulsar’s size and mass. In the process, they also managed to locate the various “hot spots” on its surface, effectively creating the first map of a neutron star.

Our eyes can’t see them, but Martian auroras are there, and more commonplace than we once thought. The Martian auroras were first discovered in 2016 by NASA’s MAVEN spacecraft. Now some new results are expanding our knowledge of these unusual auroras.

NASA has chosen the sampling site for its OSIRIS-REx spacecraft. After narrowing it down to four potential sites and examining them in detail, they’ve settled on one location. Their choice? Nightingale.

By the time a rocket actually launches, it’s components have been through a ton of rigorous testing. That’s certainly true of NASA’s SLS (Space Launch System) which is the most powerful rocket ever built. That’s right, something is finally going to surpass the Saturn V, the rocket that took Apollo astronauts to the Moon.

NASA’s OSIRIS-REx arrived at asteroid Bennu in December 2018. During the past year, it’s been imaging the surface of the asteroid extensively, looking for a spot to take a sample from. Though the spacecraft has multiple science objectives, and a suite of instruments to meet them, the sample return is the key objective.
Now, NASA has narrowed the choice down to four potential sampling locations on the surface of the asteroid.
