This Powerful Ion Engine Will Be Flying on NASA’s DART Mission to Try and Redirect an Asteroid

Despite humanity’s current struggle against the novel coronavirus, and despite it taking up most of our attention, other threats still exist. The very real threat of a possible asteroid strike on Earth in the future is taking a backseat for now, but it’s still there.

Though an asteroid strike seems kind of ephemeral right now, it’s a real threat, and one that—unlike a coronavirus—has the potential to end humanity. Agencies like NASA and the ESA are still working on their plans to protect us from that threat.

NASA Chooses 4 New Astronomy Space Missions for Additional Study

Since 1958, the NASA Explorer Program has conducted low-cost missions that were deemed relevant to the goals of the Science Mission Directorate (SMD), particularly where the study of our Sun and the deeper cosmic mysteries are concerned. Recently, the Explorer Program selected four missions that they considered to be well-suited to these goals, two of which will be selected for launch in the coming years.

Consisting of two astrophysics Small Explorer (SMEX) and two Missions of Opportunity (MO) proposals, these missions are designed to study cosmic explosions and the debris they leave behind, as well as monitor how nearby stellar flares may affect the atmospheres of orbiting planets. After detailed evaluations, two of these missions will be selected next year and will take to space sometime in 2025.

The Lunar Gateway is No Longer a Required Part of the Artemis Mission to Return to the Moon by 2024

In 2010, President Barack Obama signed the NASA Authorization Act, which charged NASA with developing all the necessary technologies and components to allow for a crewed mission to Mars. Key to this was the development of the Space Launch System (SLS), the Orion spacecraft, and an orbiting lunar habitat (aka. the Lunar Gateway).

However, in recent years, these plans have been altered considerably to prioritize “returning to the Moon.” Formally named Project Artemis, VP Pence emphasized in March of 2019 that NASA must return to the Moon by 2024, even if it meant some shakeups were needed. In the latest news, NASA has indicated that the Lunar Gateway is no longer a priority, as part of a plan to “de-risk” the mandatory tasks associated with Artemis.

NASA tells Boeing to Make 61 Corrective Actions to Starliner Before the Program can Continue

With the retirement of the Space Shuttle in 2011, NASA has become dependent on its Russian counterparts to send and return astronauts to the International Space Station (ISS). Hoping to restore domestic launch capability to American soil, NASA has contracted with aerospace developers like SpaceX and Boeing to develop crew-capable spacecraft, as part of their Commercial Crew Program (CCP).

After years of development, Boeing managed to get their CST-100 Starliner ready for its first uncrewed test flight on December 20th, 2019. Unfortunately, a hiccup occurred during the mission that prevented the spacecraft docking with the ISS. After an independent review of the mission, NASA and Boeing have determined that 61 corrective actions need to be taken before the Starliner can fly again.

Good News! The New Strategy of Using InSight’s Arm to Push the Mole Seems to be Making Progress.

There’s at least one small bit of good news in these challenging Covid-19 times. And it’s playing out on the surface of Mars. In a brief Tweet, NASA says that using InSight’s robotic arm to push the Mole into the ground is working, somewhat.

OSIRIS-REx did its Closest Flyover Yet, just 250 Meters Above its Sample Site

NASA’s OSIRIS-REx is getting closer, physically and temporally, to its primary goal. The spacecraft arrived at Bennu at the end of 2018, and for just over a year it’s been studying the asteroid, searching for a suitable sampling site. To do that, it’s getting closer and closer.

Comparing Mountains on the Moon to the Earth’s Peaks

NASA’s Artemis Program is planning to land astronauts on the Moon’s south pole. To prepare for this, NASA’s Solar System Exploration Research Virtual Institute (SSERVI) is creating the Lunar South Pole Atlas (LSPA). As part of that Atlas, NASA is mapping the topography of the region, including the mountains.

WFIRST Passes an Important Milestone, it’s Time to Begin Development and Testing

Soon, astronomers and astrophysicists will have more observing power than they know what to do with. Not only will the James Webb Space Telescope one day, sometime in the next couple years, we hope, if all goes well, and if the coronavirus doesn’t delay it again, launch and begin operations. But another powerful NASA space telescope called WFIRST has passed an important stage, and is one step closer to reality.

NASA is Planning to Build a Lunar Rover With a 1-Meter Drill to Search for Water Ice

Meet VIPER, NASA’s new lunar rover, equipped with a drill to probe the Moon’s surface and look for water ice. VIPER, or Volatiles Investigating Polar Exploration Rover, will carry a one-meter drill and will use it to map out water resources at the Moon’s south pole. It’s scheduled to be on the lunar surface by December 2023, one year later than it’s initial date.

The Life of Katherine Johnson Shows that ‘Hidden Figures’ Are Important to History

NASA mathematician Katherine Johnson did more than just calculate rocket trajectories for early space missions. Her story, when it was finally told, completely changed people’s perceptions about who has been – and who can be — important in history.
