Where’s Waldo (or Where’s Wally) is a very popular book series for all ages. One way to make it potentially more interesting is to adapt it to interplanetary exploration by searching for a Martian rover in a picture taken from a Martian helicopter. Ingenuity took a picture on its eleventh flight that would be a worthy addition to any interplanetary search game – in this image, the goal is to find Perseverance.

In March of 2019, NASA was directed to develop all the necessary equipment and planning to send astronauts back to the Moon by 2024. This plan, officially named Project Artemis, was part of an agency-wide shakeup designed to ensure that the long-awaited return to the Moon takes place sooner than NASA had originally planned. In accordance with their “Moon to Mars” framework, NASA hoped to assemble the Lunar Gateway first, then land astronauts on the surface by 2028.
Astronomers have an excellent habit of naming large projects after deserving contributors to their field. From Nancy Grace Roman to Edwin Hubble, some of the biggest missions are named after space exploration pioneers. When ESA and JAXA sat down to figure out a name for their new Mercury probe, they would have come across an important name early in their research – Giuseppe “Bepi” Colombo – the man who helped plan the Mariner 10 Mercury mission.

In 2014, the UN Intergovernmental Panel on Climate Change (IPCC) released its Fifth Assessment Report (AR5). As with previous reports, AR5 contained the latest findings of Climate Change experts from all relevant disciplines, as well as projections about the near future. In short, the AR5 and its predecessors were assessments of the impact anthropogenic Climate Change was having on the planet and how we could avoid worst-case scenarios.
Want to try living on Mars, but not sure you want to experience the nine-month flight time to get there? NASA is looking for applicants to serve as crew members for a one-year analog mission in a habitat to simulate life on the Red Planet, beginning in Fall 2022. All you have to do is get to Houston, Texas, and you’ll even get paid.

In a few years, NASA will be sending astronauts to the Moon for the first time since the Apollo Era (1969-1972). As part of the Artemis Program, the long-term goal is to create the necessary infrastructure for a “sustained program of lunar exploration.” The opportunities this will present for lunar research are profound and will likely result in new discoveries about the formation and evolution of the Moon.
The universe is littered with supermassive black holes. There’s one a mere 30,000 light-years away in the center of the Milky Way. Most galaxies have one, and some of them are more massive than a billion stars. We know that many supermassive black holes formed early in the universe. For example, the quasar TON 618 is powered by a 66 billion solar mass black hole. Since its light travels nearly 11 billion years to reach us, TON 618 was already huge when the universe was just a few billion years old. So how did these black holes grow so massive so quickly?
Two spacecraft made historic flybys of Venus last week, and both sent back sci-fi-type views of the mysterious, cloud-shrouded planet.
In 1905 Albert Einstein wrote four groundbreaking papers on quantum theory and relativity. It became known as Einstein’s annus mirabilis or wonderous year. One was on brownian motion, one earned him the Nobel prize in 1921, and one outlined the foundations of special relativity. But it’s Einstein’s last 1905 paper that is the most unexpected.
Over the past few weeks, there was quite a bit of excitement in the air at the NASA Jet Propulsion Laboratory in Pasadena, California, where mission controllers were prepping the Perseverance rover to acquire its first sample from the Martian surface. This mission milestone would be the culmination of years of hard work by a team of over 90 dedicated scientists and engineers.
One of the reasons the ISS is still alive and kicking is that it offers a unique environment for testing that is available nowhere, either on the Earth or off of it. Plenty of science experiments want to take advantage of that uniqueness. This week, a fresh crop of experiments was delivered to the ISS aboard a Northrop Grumman Cygnus resupply craft. They range from 3D printers to a high school science experiment with mold, and now they each have the opportunity to make use of the ISS’s microgravity environment.
As any good project manager will tell you, goals are necessary to complete any successful project. The more audacious the goal, the more potentially successful the project will be. But bigger goals are harder to hit, leading to an increased chance of failure. So when the team behind one of NASA’s most unique missions released a list of goals this week, the space exploration world took notice. One thing is clear – Dragonfly will not lack ambition.
Asteroid Bennu is one of the two most hazardous known asteroids in our Solar System. Luckily, the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) spacecraft orbited Bennu for more than two years and gathered data that has allowed scientists to better understand the asteroid’s future orbit, trajectory and Earth-impact probability, and even rule out some future impact possibilities.
As we all anticipate the launch of the James Webb Space Telescope (JWST) later this year (hopefully), LEGO designers are hoping for a “launch” of their own. A new LEGO design of JWST is currently gathering supporters on the LEGO Ideas website. If it gets enough support, LEGO will review it and possibly create it.
When it comes to finding exoplanets, size matters, but so does weight. The larger and heavier the planet, the more likely they will be discovered by the current crop of telescopes. Both the techniques to find exoplanets and the telescopes using those techniques are biased toward larger, heavier planets. So when even the current crop of telescopes manages to find one that is about half the mass of Venus, it is cause for celebration. That is precisely the size of the planet a team from the European Southern Observatory’s Very Large Telescope has found orbiting a star called L98-59.
Photos can’t do some places justice – nor can any level of sophisticated remote sensing. That seems to be the case for Gale Crater. Curiosity has been wandering around the crater for almost the last nine years. Scientists thought Gale crater was an old lakebed, and it was specifically chosen as a landing site to allow Curiosity to collect samples from such a lakebed. But new research from scientists at the University of Hong Kong shows that most likely, the samples Curiosity has been analyzing during its sojourn didn’t actually form in a lake.

If you’re a fan of the Search for Extraterrestrial Intelligence (SETI) and the Fermi Paradox, then it’s likely you’ve heard of a concept known as the Great Filter. In brief, it states that life in the Universe may be doomed to extinction, either as a result of cataclysmic events or due to circumstances of its own making (i.e., nuclear war, climate change, etc.) In recent years, it has been the subject of a lot of talk and speculation, and not just in academic circles.
