Mars
Mars is the second smallest planet in our solar system and the fourth planet from the sun. Iron oxide is prevalent in Mars' surface resulting in its reddish color and its nickname "The Red Planet." Mars' name comes from the Roman god of war.
” data-gt-translate-attributes=”["attribute":"data-cmtooltip", "format":"html"]”>Mars, there are also many scientific investigations on the agenda.
In fact, that list is growing, as NASA just selected two new instruments for priority Artemis science on the moon. One is called Lunar Vulkan Imaging and Spectroscopy Explorer (Lunar-VISE) and its goal is to explore the mysterious Gruithuisen Domes. What makes these geological features so puzzling to scientists is that they appear to have been formed by a magma rich in silica, similar in composition to granite.
How did these silicic magmas form on the moon, when silicic volcanoes on Earth typically form in the presence of both water and plate tectonics?
Adding to the growing list of commercial deliveries slated to explore more of the Moon than ever before under Artemis, NASA has selected two new science instrument suites, including one that will study the mysterious Gruithuisen Domes for the first time.
These payload suites mark the second selection through the agency’s Payloads and Research Investigations on the Surface of the Moon (PRISM) call for proposals. Both payloads will be delivered to the lunar surface on future flights through NASA’s Commercial Lunar Payload Services (CLPS) initiative, which is one part of the agency’s larger lunar exploration architecture planned for this decade.
“The two selected studies will address important scientific questions related to the Moon,” said Joel Kearns, deputy associate administrator for exploration in NASA’s Science Mission Directorate. “The first will study geologic processes of early planetary bodies that are preserved on the Moon, by investigating a rare form of lunar volcanism. The second will study the effects of the Moon’s low gravity and radiation environment on yeast, a model organism used to understand <span class="glossaryLink" aria-describedby="tt" data-cmtooltip="
DNA
DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

The Lunar Vulkan Imaging and Spectroscopy Explorer (Lunar-VISE) investigation consists of a suite of five instruments, two of which will be mounted on a stationary lander and three mounted on a mobile rover to be provided as a service by the CLPS vendor.
Over the course of 10 Earth days (one lunar day), Lunar-VISE will explore the summit of one of the Gruithuisen Domes. These domes are suspected to have been formed by a sticky magma rich in silica, similar in composition to granite. On Earth, formations like these need oceans of liquid water and plate tectonics to form, but without these key ingredients on the Moon, lunar scientists have been left to wonder how these domes formed and evolved over time.
By analyzing the lunar regolith at the top of one of these domes, the data collected and returned by Lunar-VISE’s instruments will help scientists answer fundamental open questions regarding how these formations came to be. The data also will help inform future robotic and human missions to the Moon. Dr. Kerri Donaldson Hanna of the University of Central Florida will lead this payload suite.
The second selected investigation, the Lunar Explorer Instrument for space biology Applications (LEIA) science suite, is a small CubeSat-based device. LEIA will provide biological research on the Moon – which cannot be simulated or replicated with high fidelity on the Earth or International Space Station – by delivering the yeast Saccharomyces cerevisiae to the lunar surface and studying its response to radiation and lunar gravity. S. cerevisiae is an important model of human biology, especially in the areas of genetics, cellular and molecular replication and division processes, and DNA damage response to environmental factors such as radiation. The data returned by LEIA, in conjunction with previously existing data from other biological studies, could help scientists answer a decades-old question of how partial gravity and actual deep space radiation in combination influence biological processes. Dr. Andrew Settles of NASA’s Ames Research Center in Silicon Valley, California will lead the LEIA payload suite.
With these selections in place, NASA will work with the CLPS office at the agency’s Johnson Space Center in Houston to issue task orders to deliver these payload suites to the Moon in the 2026 timeframe.
For these payload suites, the agency also has selected two project scientists to coordinate science activities for the selected instrument suites, including working with the payloads on landing site selection, developing concepts of operations, and archiving science data acquired during surface operations. Dr. John Karcz of NASA Ames Research Center in California will coordinate the Lunar-VISE investigation suite for delivery to the Gruithuisen Domes, and Dr. Cindy Young of NASA’s Langley Research Center in Hampton, Virginia, will coordinate the LEIA investigation suite for delivery.
CLPS is a key part of NASA’s Artemis lunar exploration plans. The science and technology payloads sent to the Moon’s surface will help lay the foundation for human missions on and around the Moon. The agency has made seven task order awards to CLPS providers for lunar deliveries between in the early 2020s with more delivery awards expected through 2028.
NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.
Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.
She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.
Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.
“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.
It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.
Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.
Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.
Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.
“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.
He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.
Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.
TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.
Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.
Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.
The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.
The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.
It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.
Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.
Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.
Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.
Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.
Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.
The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
