NASA is commonly thought of as America’s space agency, but its name also emphasizes another research area. The National Aeronautics and Space Administration is also America’s civilian aerospace research organization. In that role, it has been instrumental in developing new technologies ranging from rocket engines to aircraft control systems. Part of that role is running the Advanced Air Mobility (AAM) campaign to test autonomous drone technology. The latest milestone in that campaign was testing an electric vertical takeoff and landing (eVTOL) helicopter intended for eventual use as an air taxi.Continue reading “NASA is Testing out a new air Taxi Prototype”
The fight over who gets to take the Artemis astronauts back to the Moon continues! It all began when NASA announced that they had awarded the contract for its Human Landing System (HLS), the reusable lunar lander that would ferry the Artemis III astronauts to the lunar surface. This decision did not sit well with the other two finalists, Blue Origin and Dynetics, who appealed the decision because NASA was showing “favoritism.”
The Government Accountability Office (GAO) rejected these appeals, which has prompted Blue Origin founder Jeff Bezos to bring out the big guns. In addition to filing a lawsuit in federal court and lobbying Congress, they have also waged a public relations war against SpaceX itself, calling their safety record and into question. In response, Elon Musk took to Twitter to address Blue Origin’s claims and set the record straight.Continue reading “Musk Says That Refueling Starship for Lunar Landings Will Take 8 Launches (Maybe 4)”
In March of 2019, NASA was directed to develop all the necessary equipment and planning to send astronauts back to the Moon by 2024. This plan, officially named Project Artemis, was part of an agency-wide shakeup designed to ensure that the long-awaited return to the Moon takes place sooner than NASA had originally planned. In accordance with their “Moon to Mars” framework, NASA hoped to assemble the Lunar Gateway first, then land astronauts on the surface by 2028.
Unfortunately, this ambitious proposal has led to all sorts of complications and forced NASA to shift certain priorities. Most recently, NASA’s Office of Inspector General (OIG) submitted a report that indicated that their new Exploration Extravehicular Mobility Units (xEMU) spacesuits will not be ready in time. The resulting delay has prompted Elon Musk to offer the services of SpaceX to expedite the spacesuit’s development and get Artemis back on schedule.Continue reading “2024 Artemis Landings Could Slip Because of a Lack of Spacesuits. Musk Offers to Develop Them”
Want to try living on Mars, but not sure you want to experience the nine-month flight time to get there? NASA is looking for applicants to serve as crew members for a one-year analog mission in a habitat to simulate life on the Red Planet, beginning in Fall 2022. All you have to do is get to Houston, Texas, and you’ll even get paid.Continue reading “Can you Last a Year on Mars? NASA is Recruiting Crew for a Year-Long Analog Mission”
Over the past few weeks, there was quite a bit of excitement in the air at the NASA Jet Propulsion Laboratory in Pasadena, California, where mission controllers were prepping the Perseverance rover to acquire its first sample from the Martian surface. This mission milestone would be the culmination of years of hard work by a team of over 90 dedicated scientists and engineers.
The commands to commence operations to take its first sample (from drill site Roubion) were sent to the rover on Sol 164 (Thurs, Aug. 5th). On the morning of Friday, Aug. 6th, the team gathered to witness the sampling data come in. Everything appeared to be fine until they were notified a few hours later that the sample tube was empty! Since then, the rover’s science and engineering teams have been investigating what could have become of the sample.Continue reading “Perseverance Fails to Collect its First Sample”
If you’re a fan of the Search for Extraterrestrial Intelligence (SETI) and the Fermi Paradox, then it’s likely you’ve heard of a concept known as the Great Filter. In brief, it states that life in the Universe may be doomed to extinction, either as a result of cataclysmic events or due to circumstances of its own making (i.e., nuclear war, climate change, etc.) In recent years, it has been the subject of a lot of talk and speculation, and not just in academic circles.
Stephen Hawking and Elon Musk have also weighed in on the issue, claiming that humanity’s only chance at long-term survival is to become “interplanetary.” Addressing this very possibility, a research team led by NASA’s Jet Propulsion Laboratory (JPL) recently created a timeline for potential human expansion beyond Earth. According to their findings, we have the potential of going interplanetary by the end of the century and intragalactic by the end of the 24th!Continue reading “Avoiding the Great Filter. How Long Until We’re Living Across the Solar System?”
On July 20th, 2021, NASA’s Juno spacecraft conducted a flyby of Jupiter’s (and the Solar System’s) largest moon, Ganymede. This close pass was performed as part of the orbiter’s thirty-fourth orbit of the gas giant (Perijove 34), which saw the probe come within 50,109 km (31,136 mi) of the moon’s surface. The mission team took this opportunity to capture images of Ganymede’s using Juno’s Jovian Infrared Auroral Mapper (JIRAM).
These were combined with images acquired during two previous flybys to create a new infrared map of Ganymede’s surface, which was released in honor of the mission’s tenth anniversary (which launched from Earth on Aug. 5th, 2011). This map and the JIRAM instrument could provide new information on Ganymede’s icy shell and the composition of its interior ocean, which could shed led on whether or not it could support life.Continue reading “Ganymede in Infrared Taken During Juno’s Most Recent Flyby”
In May of 2018, NASA’s Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) landed on the Martian surface. This mission is the first of its kind, as all previous orbiters, landers, and rovers focused on studying the surface and atmosphere of Mars. In contrast, InSight was tasked with characterizing Mars’ interior structure and measuring the core, mantle, and crust by reading its seismic activity (aka. “marsquakes”).
The purpose of this is to learn more about the geological evolution of Mars since it formed 4.5 billion years ago, which will also provide insight into the formation of Earth. According to three recently published papers, the data obtained by InSight has led to new analyses on the depth and composition of Mars’ crust, mantle and confirmed the theory that the planet’s inner core is molten.Continue reading “InSight has Mapped out the Interior of Mars, Revealing the Sizes of its Crust, Mantle, and Core”
In the coming decade, NASA and the ESA will be sending two dedicated missions that will explore Jupiter’s moon Europa. These missions are known as the Europa Clipper and the JUpiter ICy moons Explorer (JUICE) missions, which will fulfill a dream that has been decades in the making – searching for possible evidence of life inside Europa. Since the 1970s, astronomers have theorized that this satellite contains a warm-water ocean that could support life.
The case for life in Europa has only been bolstered thanks to multiple flybys and observation campaigns that have been mounted since. According to new research led by the University of Hawaii at Manoa, the best way to look for potential signs of life (aka. biosignatures) would be to analyze small impact craters on Europa’s surface. These patches of exposed subsurface ice could point the way towards life that might exist deeper in the moon’s interior.Continue reading “Micrometeorites Churn up the Surface of Europa. If you Want to Find Life, You’ll Need to dig Down a Meter or So”
Things are not looking very good for the Hubble Space Telescope right now. On Sunday, June 13th, the telescope’s payload computer suddenly stopped working, prompting the main computer to put the telescope into safe mode. While the telescope itself and its science instruments remain in working order, science operations have been suspended until the operations team can figure out how to get the payload computer back online.
While attempting to restart the computer, the operations team has also tried to trace the issue to specific components in the payload computer and switch to their backup modules. As of June 30th, the team began looking into the Command Unit/Science Data Formatter (CU/SDF) and the Power Control Unit (PCU). Meanwhile, NASA is busy preparing and testing procedures to switch to backup hardware if either of these components are the culprit.Continue reading “NASA Continues to Try and Rescue Failing Hubble”
