The 5-foot-tall (1.5 meters) Beresheet fired its engines for a little over a minute early this morning (April 1), altering its trajectory slightly to prepare for a planned capture into lunar orbit on Thursday (April 4).
If all goes according to plan, the robotic lander will touch down on the moon one week later, on April 11. That will be a huge milestone. To date, the only organizations to pull off a soft lunar landing are superpower governments — the Soviet Union, the United States and China.

Undoing Aging in the Viewfinder

LEAF Director Elena Milova shares a report from the recent Berlin Undoing Aging conference with you today. Hosted by the Forever Healthy Foundation and SENS Research Foundation, the event saw the leading figures in aging research come together for this superb conference.
The day after I got back from the Undoing Aging 2019 scientific conference, which was jointly organized by the SENS Research Foundation and Forever Healthy Foundation, Moscow greeted me with the first sunny days of the spring. Still tired and lacking sleep, but happy and inspired, I want to share my impressions of this year’s conference with you.
Actually, I began preparing for this event in the autumn of 2018, when it was first announced. I booked the hotel well in advance, including some spare rooms that could be transferred to our partners later on. B&B Alexanderplatz is located next to the conference venue Umspannwerk Alexanderplatz, literally next door, and it has a nice social space in the lobby, making it very handy for setting appointments with business partners, so we at LEAF decided to make it our headquarters once again. I arrived on March 26th, got some brief rest, and went downstairs to work while also keeping an eye on who was arriving.
Not long after I sat down, I saw some very familiar faces, as Maria Entraigues-Abramson and her husband Gary Abramson arrived. As part of the organizers’ team from the SRF, they came to Berlin early to help coordinate the preparation. Next, I saw our own VP Dr. Oliver Medvedik and his super-energetic friend, Jean Lam. Last but not least, I met Anna Dobryukha, the chief of the medical department at Komsomolskaya Pravda; she is one of the most famous Russian journalists writing about aging and longevity.

India’s anti-satellite missile test created at least 400 pieces of orbital debris, the head of NASA says — placing the International Space Station (ISS) and its astronauts at risk.
NASA administrator Jim Bridenstine said Monday that just 60 pieces of debris were large enough to track. Of those, 24 went above the apogee of the ISS, the point of the space station’s orbit farthest from the Earth.
“That is a terrible, terrible thing to create an event that sends debris at an apogee that goes above the International Space Station,” Bridenstine said in a live-streamed NASA town hall meeting. “That kind of activity is not compatible with the future of human spaceflight.”

Discovering planets that nobody has ever seen before is even harder than it sounds. Space telescopes from NASA and other scientific bodies have gathered an incredible amount of data that will take astronomers years and years to sift through, and many times there’s just nothing there to be found.
But humans don’t have to do all of the work, and Anne Dattilo, a senior at the University of Texas in Austin enlisted the help of artificial intelligence to study data from NASA’s Kepler space telescope and found not one, but two new exoplanets in the process.

The most popular contender over the past few decades has been string theory, and the related concepts of superstring theory and M-theory, in which particles are considered as tiny units of one-dimensional string. However, a lesser-known theory has also gained traction; loop quantum gravity (LQG), which attempts to solve the quantum gravity problem by focusing on the very fabric of spacetime, rather than the particles themselves.
In “Quantum Space,” the popular-science writer Jim Baggott lays out the basic principles of LQG for science enthusiasts. The book looks at how loop quantum gravity has emerged by following the work of two of its leading proponents, Carlo Rovelli and Lee Smolin, and assesses where the theory is now, and where it might be going.
Although the concepts are — not surprisingly — mind-boggling, Baggott asks deep questions about the nature of the universe, what space is actually composed of, and the existence of time itself. (The book covers a lot of challenging material, however, and some prior reading may help readers find their way.)

The galaxies have never before been captured in such detail.
First discovered in 1784 by William Herschel, NGC 6052 was originally thought to be a singular galaxy that simply had an odd shape.
However, scientists eventually figured out that the “oddly shaped galaxy” 230 million light-years away was, in fact, two galaxies in the process of colliding.
Having previously been observed by the Hubble telescope with an older camera in 2015, NASA recently released a stunning image of the galaxies in even better detail.
