Cool image time! Using Mars Reconnaissance Orbiter (MRO), scientists have captured a very cool image of Curiosity in its recent travels on Mars. That picture is above, reduced and sharpened to post here.

Taken by the HiRISE (High-Resolution Imaging Science Experiment) camera aboard NASA’s Mars Reconnaissance Orbiter, the image shows Curiosity as a dark speck at the front of a long trail of rover tracks. Likely to last for months before being erased by wind, the tracks span about 1,050 feet (320 meters). They represent roughly 11 drives starting on Feb. 2 as Curiosity trucked along at a top speed of 0.1 mph (0.16 kph) from Gediz Vallis channel on the journey to its next science stop: a region with potential boxwork formations, possibly made by groundwater billions of years ago.

The overview map to the right provides some context. Curiosity’s present position is indicated by the blue dot. The yellow lines indicate the approximate section of its past travels photographed by the picture above.

According to the press release at the link, the science team is now estimating the rover will arrive at the boxwork geology in about a month.

Your smartphone apps are tracking you

The smart phone: A proven tool for spying
The smart phone: A proven tool for spying

Just one more reason I don’t own a smartphone: Researchers have now found that though there is no evidence that big software companies like Facebook and Google are tracking your smartphone conversations, the data instead shows that the many apps you routinely install on your phone are spying on you quite extensively by periodically taking screenshots of things you look at and sending those images to third parties.

“There were no audio leaks at all – not a single app activated the microphone,” said Christo Wilson, a computer scientist working on the project. “Then we started seeing things we didn’t expect. Apps were automatically taking screenshots of themselves and sending them to third parties. In one case, the app took video of the screen activity and sent that information to a third party.”

Out of over 17,000 Android apps examined, more than 9,000 had potential permissions to take screenshots. And a number of apps were found to actively be doing so, taking screenshots and sending them to third-party sources. “That has the potential to be much worse than having the camera taking pictures of the ceiling or the microphone recording pointless conversations,” said David Choffnes, another computer scientists working on the project. “There is no easy way to close this privacy opening.”

Doing this kind of spying is simply unethical, but it is also now routine in our increasingly unethical culture. What makes it worse is that I expect few will react in any way to this information. People will shrug and continue to install apps casually, accepting the fact that they are now merely a tool that someone else can manipulate.

Rocket startup MaiaSpace picks Polish institute to build its rocket’s upper stage engine

10:24 am

The smallsat rocket startup MaiaSpace has selected Poland’s Łukasiewicz Research Network’s Institute of Aviation to develop the engine that will power its Maia rocket’s top stage, used to put satellites into their final orbit.

In a 23 April update, the Łukasiewicz Research Network’s Institute of Aviation (Łukasiewicz–ILOT) announced that it had been selected by MaiaSpace to develop a rocket engine to power Maia’s Colibri kick stage. According to the announcement, the engine will be based on technology developed by Łukasiewicz–ILOT as part of its Green Bipropellant Apogee Rocket Engine (GRACE) initiative, a project financed by the European Space Agency under the Future Launchers Preparatory Programme.

Each new engine will be capable of producing 420 newtons of thrust, with a cluster of these engines powering the Colibri kick stage. However, the update did not specify how many engines would make up the cluster

MaiaSpace had previously indicated it was building its own Colibri kick stage engine. It appears that it has now decided to hire Lukasiewicz to do it instead.

The significance here is not this specific decision, but how it involves two different European commercial entities with no managerial input from the European Space Agency or any government agency. It really does appear that Europe’s aerospace industry has completely freed itself from the dictates of those government apparachiks.

MaiaSpace hopes to complete the first launch of Maia in 2026.

Trump cuts apparently shutting down NASA’s climate office in New York

Schmidt's data tampering, as documented in 2017
Schmidt’s data tampering, as documented in 2016.

As part of the Trump administration’s aggressive effort to trim the federal budget as well as shift the research focus at the federal government’s many science agencies, on April 24, 2025 it revealed that it has canceled the building lease for the Goddard Institute for Space Studies (GISS) in New York that has existed since 1961 and in 2016 and 2017 was found to be tampering with past climate data with no explanation, lowering past temperature numbers while raising more recent ones in order to make the data fit the as-yet unproven theory that human activity is causing global warming.

Those “adjustments” have never been justified in any way. Nor has Gavin Schmidt, the man who heads GISS, ever done anything to correct them. Moreover, when his office was accused of this tampering in 2016 he not only refused to fix or justify the changes, he responded by claiming “planetary warming does not care about the election.” In the years since it has been his office that annually declares each year “the hottest on record,” using these tampered numbers to do so and demonstrating that he has been acting not as a real researcher but as a political operative of the global warming crowd.

Though the office lease is being canceled, GISS has not been shut down, as of now.

While NASA is terminating the lease on the GISS offices, it is not closing the institute itself. Lystrup said in the email that it will help employees move “to remote work agreements in the short-term as the agency seeks a new, permanent space for the team.”

I suspect this statement is merely designed by Trump officials to dampen the screams of opposition against its actions. It is very likely GISS is going away, and most of its employees will have to find new jobs.

The hope is that new scientists can be hired to review these tampered numbers and get them fixed so that climate research in the future can proceed with reliable data.

A telescope picture of blackness

A dust cloud in space
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was released today by the science team running the Dark Energy Camera on the Blanco 4-meter telescope in Chile.

This winding, shadowy form, accentuated by a densely-packed starry background, is the Circinus West molecular cloud — a region rich in gas and dust and known for its host of newly formed stars. Molecular Clouds, the cradles of star formation, are interstellar clouds that are so dense and cold that atoms within them bond with each other to form molecules. Some, such as Circinus West, are so dense that light cannot pass through, giving them a dark, mottled appearance and earning them the name dark nebulae. The cloud’s flourishing population of young stars has offered astronomers a wealth of insight into the processes driving star formation and molecular cloud evolution.

…Circinus West is known for harboring dozens of young stellar objects — stars that are in their early stages of development. Despite being shrouded in dense gas and dust, these infant stars make themselves known. Zooming in, various clues to their presence can be seen dotted throughout Circinus West’s snaking tendrils.

The cloud is about 2,500 light years away and is estimated to be about 180 light years across. Scientists estimate the mass in the cloud to be about 250,000 times that of the Sun.

No one however would ever even know this cloud existed if it wasn’t back dropped by thick field of stars behind it.

Ispace’s Resilience lunar lander completes all maneuvers prior to entering lunar orbit

Ispace’s Resilience

The Japanese startup Ispace today announced that its Resilience lunar lander — launched on a Falcon 9 to the Moon in January — has now completed all the orbital maneuvers required to send it on a path to enter lunar orbit in early May.

Ispace engineers performed the final orbit maneuver from the Mission Control Center in Nihonbashi, Tokyo, Japan in accordance with the mission operation plan. In total, the RESILIENCE lunar lander has completed 8 orbit control maneuvers. RESILIENCE is now maintaining a stable attitude in its planned orbit and mission operations specialists are now preparing for the Mission 2 milestone Success 7, “Entering Lunar Orbit.” The RESILIENCE lander is expected to enter lunar orbit on May 7, 2025.

The map to the right shows the landing zone, near the top of Moon’s near hemisphere in the region of Figoris Mare. The landing will occur a week or so after orbital insertion, after the company’s engineers have fully assessed the situation.

The rover carries eight commercial payloads, including its own Tenacious mini-rover, as well as a “water electrolyzer” from a Japanese company, a “food production experiment” from another company, and a “deep space radiation probe” from the National Central University of Taiwan.

Resilience’s main purpose however remains to prove the company can build and successfully soft land on the Moon. Its only previous attempt, Hakuto-R1, crashed in Atlas Crater. Despite that failure Ispace has won a contract each from NASA and Japan to launch additional lunar landers, so a success here is critical for the company’s future.

Viasat wins contract to build ESA lunar communications constellation

1:20 pm

As part of a larger European Space Agency (ESA)) project, Viasat has won an ESA contract to build a communications constellation that will orbit the Moon.

Viasat will be responsible for the design and development of the communication network and will lead the definition of the end-to-end communications services: aiming to provide a communications network for lunar landers, rovers, orbiters, and other technology. Viasat will also be responsible for the communication earth ground infrastructure and communication lunar surface user terminals. Telespazio, as Moonlight program lead, has executed a contract with Viasat for the initial design phase of the communication system. This work will be fully funded by the European Space Agency throughout Phase 1.

The UK Space Agency, as one of the major contributors to ESA’s Moonlight program, selected Viasat to lead the UK ecosystem to deliver the communications capability. Moonlight services will be deployed in phases, targeting initial capability at the end of 2028 with full operations aimed by 2030.

It does seem that there are a lot of competing communications/navigation constellations under development, from China, Europe, and the U.S. It also appears that there is far less coordination between them then there should be.

China accelerates its schedule for its upcoming Moon/Mars missions while admitting its lunar base will take longer

10:58 am

Phase I of China/Russian Lunar base roadmap
The original phase I plan of Chinese-Russian lunar
base plan, from June 2021.

The new colonial movement: In several different reports today in China’s state-run press — timed to coincide with the launch of three astronauts to Tiangong-3 — Chinese officials confirmed that it has moved up the planned launch dates for both its first lunar rover as well as its Mars sample return mission, and it is also expanding its offers to the international community to partner on those missions.

At the same time it let slip the fact that it will not be establishing its lunar base on the Moon in 2030, as previously claimed. Moreover, note how this so-called accelerated schedule of lunar missions is actually behind the announced timetable outlined by China and Russia in 2021, as shown on the right. None will fly by this year, as promised.

As for the news today, first China announced that its Tianwen-3 Mars sample return mission will launch in 2028.
