TOKYO (Earth-Life Science Institute PR) — Earth’s Moon has a ‘near side’ that is perpetually Earth-facing and a ‘far side’, which always faces away from Earth. The composition of the Moon’s near side is oddly different from its far side, and scientists think they finally understand why.
The Earth-Moon system’s history remains mysterious. Scientists believe the two formed when a Mars-sized body collided with the proto-Earth. Earth ended up being the larger daughter of this collision and retained enough heat to become tectonically active. The Moon, being smaller, likely cooled down faster and geologically ‘froze’. The apparent early dynamism of the Moon challenges this idea.
The contrast was jarring. In one browser window, two NASA astronauts were making their way to the International Space Station (ISS) after the first orbital launch of a crew from U.S. soil in nearly 9 years.
In another window, scenes of chaos played out as protests over the death of George Floyd after his arrest by Minneapolis police erupted into violent clashes across the country.
New Horizons Mission Update by Alan Stern Principal Investigator
New Horizons is healthy and performing perfectly as it flies deeper and deeper into the Kuiper Belt! Recently we conducted an engineering review of the spacecraft to “trend” how it was working compared to when it was launched. The result was amazing: Every system and science instrument aboard New Horizons is working as well as it did when we lifted off, more than 14 years and almost 5 billion miles ago. As mission principal investigator I could not be prouder — the men and women who designed, built and tested New Horizons literally created a masterpiece of American workmanship that will likely be able to perform and explore for many more years and many more miles!
WASHINGTON (NASA PR) — In 1970, the United States Clean Air Act underwent major revisions to reduce pollution and protect air quality, President Nixon created the Environmental Protection Agency, and NASA scientists were cracking open the door on a new era of studying our home planet from space.
The first black-and-white satellite images of Earth were just ten years old: a swirling mass of white clouds over back oceans. The first measurements of Earth’s temperature from space were made just a year prior in 1969 by Nimbus 3, a joint mission with the National Oceanic and Atmospheric Administration, which became a major step in improving weather forecasts.
MOUNTAIN VIEW, Calif. (SETI Institute PR) — In a new paper published in the Astrophysical Journal Letters, co-authored by SETI Institute scientist Jeff Coughlin, astronomers using Kepler data have identified a planet nearly the same size of Earth that orbits in its star’s habitable zone, where liquid water could exist on its surface.
This new world, Kepler-1649c, is 300 light-years away and orbits a star that is about one-fourth the size of our Sun. Only 6% bigger than the Earth, it shares its sun with a planet much like Venus, Kepler-1649b, which was discovered three years ago. Although NASA’s Kepler space telescope was retired in 2018 when it ran out of fuel, scientists are still making discoveries as they continue to examine the signals Kepler detected.
PARIS (ESA PR) — The ESA/JAXA BepiColombo mission completed its first flyby on 10 April, as the spacecraft came less than 12 700 km from Earth’s surface at 06:25 CEST, steering its trajectory towards the final destination, Mercury. Images gathered just before closest approach portray our planet shining through darkness, during one of humankind’s most challenging times in recent history.
PARIS (ESA PR) — As part of the ongoing commitment to realise new satellite missions that advance our understanding of Earth, contribute to climate research, benefit society and demonstrate innovative space technologies, ESA soon expects to release a Call for Ideas for Earth Explorer 11, pending approval from Member States at the Programme Board for Earth Observation. The hope is to issue the Call before the end of May, with a deadline to submit full proposals by the end of October 2020.
WASHINGTON (NOAA PR) — GOES-16 and GOES-17, also known as GOES-East and GOES-West respectively, provide beautiful images of Earth. However, what you see on your television, computer, and mobile device are digital representations of the data these satellites capture, not actual photographs or videos. So how are these images created?
NASA to fulfill Boston University study of the earth’s magnetic field, as TriSept leads integration of 6U CubeSat payload in dispenser bound for launch on a Rocket Lab Electron.
CHANTILLY, Virginia, March 9, 2020 (TriSept PR) – TriSept Corporation, a leading provider of launch integration, management and brokerage services for commercial and government missions, today announced it has completed the integration activity for NASA’s ELaNa 32 ANDESITE mission, a rideshare set to launch Boston University’s groundbreaking scientific study of the earth’s magnetic field on a Rocket Lab Electron from New Zealand later this month.
PASADENA, Calif. (NASA PR) — Sue Smrekar really wants to go back to Venus. In her office at NASA’s Jet Propulsion Laboratory in Pasadena, California, the planetary scientist displays a 30-year-old image of Venus’ surface taken by the Magellan spacecraft, a reminder of how much time has passed since an American mission orbited the planet. The image reveals a hellish landscape: a young surface with more volcanoes than any other body in the solar system, gigantic rifts, towering mountain belts and temperatures hot enough to melt lead.
GREENBELT, Md. (NASA PR) — An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids – the parent bodies of many meteorites – can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s building blocks.
WASHINGTON (NASA PR) — NASA released a report Friday with recommendations from the Planetary Protection Independent Review Board (PPIRB) the agency established in response to a recent National Academies of Sciences, Engineering, and Medicine report and a recommendation from the NASA Advisory Council.
With NASA, international, and commercial entities planning bold missions to explore our solar system and return samples to Earth, the context for planetary protection is rapidly changing. NASA established the PPIRB to conduct a thorough review of the agency’s policies.
Planetary protection establishes guidelines for missions to other solar system bodies so they are not harmfully contaminated for scientific purposes by Earth biology and Earth, in turn, is protected from harmful contamination from space.
The board’s report assesses a rapidly changing environment where more samples from other solar system bodies will be returned to Earth, commercial and international entities are discussing new kinds of solar system missions, and NASA’s Artemis program is planning human missions to the Moon and eventually to Mars.
The report discusses 34 findings, and 43 recommendations from the PPIRB, which was chaired by planetary scientist Alan Stern of the Southwest Research Institute to address future NASA missions and proposed missions by other nations and the private sector that include Mars sample return, robotic missions to other bodies, eventual human missions to Mars, and the exploration of ocean worlds in the outer solar system.
“The landscape for planetary protection is moving very fast. It’s exciting now that for the first time, many different players are able to contemplate missions of both commercial and scientific interest to bodies in our solar system,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “We want to be prepared in this new environment with thoughtful and practical policies that enable scientific discoveries and preserve the integrity of our planet and the places we’re visiting.”
The PPIRB, comprised of a high-level team of 12 experts and stakeholders from science, engineering and industry, examined how to update planetary protection policies and procedures in light of current capabilities. Such guidelines have periodically been updated and inform exploration by spacefaring nations that have signed the Outer Space Treaty since the 1960s.
“Planetary science and planetary protection techniques have both changed rapidly in recent years, and both will likely continue to evolve rapidly,” Stern said. “Planetary protection guidelines and practices need to be updated to reflect our new knowledge and new technologies, and the emergence of new entities planning missions across the solar system. There is global interest in this topic, and we also need to address how new players, for example in the commercial sector, can be integrated into planetary protection.”
NASA plans to begin a dialogue about the PPIRB report’s recommendations with stakeholders, and international and commercial partners to help build a new chapter for conducting planetary missions, and planetary protection policies and procedures.

The first successful launch of Germany’s A-4 ballistic missile and the orbiting of the first artificial satellite, Sputnik-1, took place 15 years and one day apart. The two achievements are related in more ways than their proximity on the calendar.
On Oct. 3, 1942, an A-4 developed by Wernher von Braun and his German Army team reached an altitude of 85 to 90 km (52.8 to 55.9 miles) after launch from Peenemunde on the Baltic Coast.
VANDENBERG AIR FORCE BASE, Calif. (NASA PR) — NASA and Northrop Grumman currently are preparing the agency’s Ionospheric Connection Explorer, or ICON, spacecraft and the Pegasus XL rocket at Vandenberg Air Force Base in California for ferry to the Cape Canaveral Air Force Station in Florida by the L-1011 Stargazer aircraft on Oct. 1, 2019.
The launch has been rescheduled to Oct. 10, 2019, following the completion of a joint NASA/Northrop Grumman investigation into a Pegasus sensor reading that was not within normal limits during previous ferry and launch attempt flights. The cause of the issue is understood, and the flight hardware has been modified to address the issue.
