Topic: NASA’s Discovery Program
While the mission team plans to continue collecting data well into 2022, the increasing dustiness of the spacecraft’s solar panels and the onset of the Martian winter led to a decision to conserve power and temporarily limit the operation of its instruments. ![]() This artist’s concept depicts NASA’s InSight lander after it has deployed its instruments on the Martian surface.

NASA’s Insight lander has probe just under the Surface of Mars
Sensors embedded in the tether are designed to measure heat flowing from the planet once the mole has dug at least 10 feet (3 meters) deep. The mission team has been working to help the mole burrow to at least that depth so that it can take Mars’ temperature. ![]() NASA’s InSight retracted its robotic arm on Oct. 3, 2020, revealing where the spike-like “mole” is trying to burrow into Mars. The copper-colored ribbon attached to the mole has sensors to measure the planet’s heat flow. In the coming months, the arm will scrape and tamp down soil on top of the mole to help it dig.

NASA’s InSight Mars Lander Weather Sensors stop working
Called the Auxiliary Payload Sensor Suite (APSS), the sensors collect data on wind speed and direction, air temperature and pressure, and magnetic fields. ![]() Among InSight’s instruments is the Auxiliary Payload Sensor Suite (APSS), which collects data on wind speed and direction, air temperature and pressure, and magnetic fields.

NASA’s proposed VERITAS spacecraft would explore the depths of Venus
Imagine Earth. Now fill the skies with thick, Sun-obscuring clouds of sulfuric acid; boil off the oceans by cranking up the temperature to 900 degrees Fahrenheit (nearly 500 degrees Celsius), and boost the air pressure high enough to flatten you like a pancake. What you now have is Venus, a rocky planet similar in size to Earth but different in almost every other way. ![]() An artist’s concept of active volcanos on Venus, depicting a subduction zone where the foreground crust plunges into the planet’s interior at the topographic trench.

NASA InSight Lander’s Arm helps it’s Mole get buried, resumes Science Activities
Akin to a 16-inch-long (40-centimeter-long) pile driver, the self-hammering mole has experienced difficulty getting into the Martian soil since February 2019. It’s mostly buried now, thanks to recent efforts to push down on the mole with the scoop on the end of the robotic arm. ![]() The movement of sand grains in the scoop on the end of NASA InSight’s robotic arm suggests that the spacecraft’s self-hammering “mole,” which is in the soil beneath the scoop, had begun tapping the bottom of the scoop while hammering on June 20, 2020.

NASA proposes Mission to travel to Neptune’s Moon Triton
Voyager 2 is the only spacecraft ever to have flown past Neptune, and it left a lot of unanswered questions. The views were as stunning as they were puzzling, revealing massive, dark plumes of icy material spraying out from Triton‘s surface. But how? Images showed that the icy landscape was young and had been resurfaced over and over with fresh material. But what material, and from where? ![]() This global color mosaic of Neptune’s moon Triton was taken in 1989 by Voyager 2 during its flyby of the Neptune system.

NASA to create concept design for Venus Atmosphere Probe
On February 13th, NASA announced that DAVINCI+, named after the visionary Renaissance artist and scientist Leonardo da Vinci, is one of four teams selected under the agency’s Discovery Program to develop concept studies for new missions in this decade to various intriguing destinations in the solar system. ![]() Maat Mons is displayed in this computer-generated, three-dimensional perspective of the surface of Venus. The viewpoint is located 634 kilometers (393 miles) north of Maat Mons at an elevation of 3 kilometers (2 miles) above the terrain. Lava flows extend for hundreds of kilometers across the fractured plains shown in the foreground to the base of Maat Mons.

NASA’s InSight Lander provides deeper understand of Mars in it’s first year
Five of the papers were published in Nature. An additional paper in Nature Geoscience details the InSight spacecraft’s landing site, a shallow crater nicknamed “Homestead hollow” in a region called Elysium Planitia. ![]() In this artist’s concept of NASA’s InSight lander on Mars, layers of the planet’s subsurface can be seen below and dust devils can be seen in the background.

NASA maneuvers Mars InSight Landers’ robotic arm to press down on the “Mole”
They hope that pushing down on the mole’s top, also called the back cap, will keep it from backing out of its hole on Mars, as it did twice in recent months after nearly burying itself. ![]() This test using an engineering model of the InSight lander here on Earth shows how the spacecraft on Mars will use its robotic arm to press on a digging device, called the “mole.” (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA picks Four Possible Missions to Study the Secrets of the Solar System
NASA’s Discovery Program invites scientists and engineers to assemble a team to design exciting planetary science missions that deepen what we know about the solar system and our place in it. ![]() The proposed Trident mission would explore Neptune’s moon Triton, seen here in a global color mosaic with an artist’s concept of an ionosphere.
