Mini robots that can roll, fly, float and swim, then morph into a single machine? Together they form Shapeshifter, a developing concept for a transformational vehicle to explore treacherous, distant worlds.

In a dusty robotics yard at NASA’s Jet Propulsion Laboratory in Pasadena, California, the Shapeshifter team is testing a 3D-printed prototype of this unusual explorer. A contraption that looks like a drone encased in an elongated hamster wheel rolls across the yard, then splits in half. Once separated, the two halves rise on small propellers, effectively becoming flying drones for aerial exploration. These 3D-printed parts are only the beginning; the team imagines a series of up to 12 robots that could transform into a swimming probe or a team of cave explorers.

Since arriving at near-Earth asteroid Bennu in December 2018, NASA’s OSIRIS-REx mission has been studying this small world of boulders, rocks, and loose rubble – and looking for a place to touch down. The goal of OSIRIS-REx is to collect a sample of Bennu in mid-2020, and return it to Earth in late 2023.

Bennu turned out to be rockier than anticipated, but mission planners have now identified four sites on its surface that are smooth enough for OSIRIS-REx to collect a sample. The mission will down-select to the final two sites – a primary and a backup – in December 2019. Like the mythological Bennu bird for which the asteroid is named, all of the candidate sample sites refer to birds that can be found in Egypt.

Mars 2020 is a Mars rover mission by NASA’s Mars Exploration Program with a planned launch on 17 July 2020, and touch down in Jezero crater on Mars on 18 February 2021. It will investigate an astrobiologically relevant ancient environment on Mars and investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials. It will cache sample containers along its route for a potential future Mars sample-return mission.

The currently unnamed Mars 2020 mission was announced by NASA on 4 December 2012 at the fall meeting of the American Geophysical Union in San Francisco. The rover’s design is derived from the Curiosity rover, and will use many components already fabricated and tested, including different scientific instruments and a core drill.

NASA’s Dragonfly rotorcraft-lander is seen approaching Saturn’s exotic moon Titan in this animation. Taking advantage of Titan’s dense atmosphere and low gravity, Dragonfly will explore dozens of locations across the icy world, sampling and measuring the compositions of Titan’s organic surface materials to characterize the habitability of Titan’s environment and investigate the progression of prebiotic chemistry.

NASA’s Lunar Reconnaissance Orbiter mission now celebrates its 10-year anniversary of being at the Moon. After launching on June 18, 2009, and entering lunar orbit on June 23rd, the spacecraft continues to collect vast amounts of data vital to our understanding of the lunar landscape and environment, our solar system, and to our future exploration goals for the Moon and Mars. This video highlights some notable facts and accomplishments of the LRO mission over the past decade, all of which are paving the way forward for reestablishing a human presence on the Moon with the newly announced Artemis program.

Helios-A and Helios-B (also known as Helios 1 and Helios 2) are a pair of probes launched into heliocentric orbit for the purpose of studying solar processes. A joint venture of West Germany’s space agency DFVLR (70 percent share) and NASA (30 percent), the probes were launched from Cape Canaveral Air Force Station, Florida, on December 10, 1974, and January 15, 1976, respectively. Built by the main contractor Messerschmitt-Bölkow-Blohm, they were the first spaceprobes built outside both the United States and the Soviet Union to leave Earth orbit.

The probes set a maximum speed record for spacecraft of 252,792 km/h (157,078 mph; 70,220 m/s). Helios-B flew 3,000,000 kilometres (1,900,000 mi) closer to the Sun than Helios-A, achieving perihelion on April 17, 1976, at a record distance of 43.432 million km (26,987,000 mi; 0.29032 AU), closer than the orbit of Mercury. Helios-B was sent into orbit 13 months after the launch of Helios-A. The Helios space probes completed their primary missions by the early 1980s, and continued to send data up to 1985. The probes are no longer functional but remain in their elliptical orbits around the Sun.
