Some new images sent home by the InSight Lander show the robotic arm and the craft’s instruments waiting on deck, on the surface of Mars. The lander is still having its systems tested, and isn’t quite ready to get to work. It’ll use its arm to deploy its science instruments, including a drill that will penetrate up to 5 meters (16 ft.) deep into the Martian surface.

When you go on a camping trip, when is it really tough? When are you really roughing it?
It is really tough if there is no supply store and no facilities at the place you are going. If you have to bring everything with you in your car then that makes it tougher.
If there is a gas station, running water and cabins for rent, then it becomes more like a rest stop on the highway.
The moon is a continent-sized place that is cold and difficult. The Moon has frozen ice. What do we do when we seriously want to research a remote continent-sized place that is cold and difficult. The example of that is Antarctica. Antarctica has McMurdo Station and dozens of other research stations.

NASA’s OSIRIS-REx spacecraft has reached its destination and is now in orbit around asteroid Bennu. The spacecraft travelled for over two years and covered more than 2 billion kms. It will spend a year in orbit, surveying the surface of the Potentially Hazardous Object (PHO) before settling on a location for the key phase of its mission: a sample return to Earth.
NASA keeps a close eye on the bacteria inhabiting the International Space Station with a program called the Microbial Observatory (M.O.) The ISS is home to a variety of microbes, some of which pose a threat to the health of astronauts. As part of their monitoring, the M.O. has discovered antibiotic resistant bacteria on the toilet seat on the ISS.

The Hubble Space Telescope is a hero in the astronomy world. And when it suffered a malfunctioning gyro on October 5th, it took a heroic effort on the part of the Hubble team to get it working again. Now we have Hubble’s first picture after its return to service.

Jezero crater is the landing spot for NASA’s upcoming 2020 rover. The crater is a rich geological site, and the 45 km wide (28 mile) impact crater contains at least five different types of rock that the rover will sample. Some of the landform features in the crater are 3.6 billion years old, making the site an ideal place to look for signs of ancient habitability.

Advanced propulsion breakthroughs are near. Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over one million miles per hour before 2050 are possible. There are surprising new innovations with technically feasible projects.
NASA Institute for Advanced Concepts (NIAC) is funding two high potential concepts. New ion drives could have ten times better in terms of ISP and power levels ten thousand times higher. Antimatter propulsion and multi-megawatt ion drives are being developed.

Ever since the Pioneer and Voyager probes passed through the Jovian system in the 1970s, NASA and other space agencies have dreamed of one-day sending a mission to Europa. Beyond Earth, it is considered one of the most promising candidates for finding life, which could exist in the subsurface ocean that lies beneath the moon’s icy crust.
One of these concepts is known as the Cool High Impact Method for Exploring Down into Europan Subsurface (ARCHIMEDES), a proposed direct-laser penetrator that will use a laser light carried by an optical fiber tether to penetrate Europa’s icy crust. This mission could provide future missions with access to the ocean that exists beneath Europa’s surface and enable the search for life there.

It’s been quite a tumultuous time for space telescopes lately! Less than a month ago, the Hubble Space Telescope went into safe mode after experiencing a mechanical failure with one of its gyroscopes (which has since been remedied). Shortly thereafter, the Chandra X-ray telescope went into safe mode as well, and for similar reasons. After three days, it’s operations team managed to get it back in working order as well.
And now, after nine years of service, NASA has officially announced that the Kepler Space Telescope will be retiring. With no fuel remaining to conduct its science observations, NASA has decided to leave the telescope in its current safe orbit (well away from Earth). Far from being a sad occasion, Kepler’s retirement is an opportunity to reflect upon the immense accomplishments of this telescope and how it revolutionized the study of exoplanets.
NASA’s Parker Solar Probe is now the closest object to the Sun that we’ve ever sent into space. On Oct. 29, 2018, at about 1:04 p.m. EDT, NASA’s probe broke the old record for the close-to-Sun distance of 42.73 million km (26.55 million miles). That record was held by the German-American Helios 2 spacecraft in 1976. And the probe will keep getting closer to the Sun.
