After a long week, there's nothing better than a healthy dose of cuteness.
Inspired by the sweet moment when TODAY anchor Savannah Guthrie's baby, Vale, first met Wrangler in the Orange Room, we asked members of our parenting community to send us photos of their own meeting the family pet for the first time.
And the results were, as you might expect, unbelievably adorable. They include many unsuspecting, occasionally unconscious tots, a few doting dogs, and some oh-so-curious kitties, too.
For your own chance to be featured in "Baby's First" round-ups or one of our other fun series, make sure to like the Today Parents page on Facebook.

NASA confirmed Thursday afternoon that its Messenger spacecraft collided into Mercury’s surface at more than 8,000 mph, creating a new crater on the planet.
“Going out with a bang as it impacts the surface of Mercury, we are celebrating Messenger as more than a successful mission,” John Grunsfeld, associate administrator for NASA’s Science Mission Directorate said. “The Messenger mission will continue to provide scientists with a bonanza of new results as we begin the next phase of this mission — analyzing the exciting data already in the archives, and unraveling the mysteries of Mercury.”
But before Messenger’s years-long mission came an end, NASA released several new photos of Mercury, as taken by the spacecraft. Some of these photos were composite imagery, combining years of data and photos collected by Messenger, according to CNET.
Here’s one of the incredible false-color images recently published by NASA. The different colors signify variations in mineral composition, topography and other factors on Mercury’s surface.
io9 reports that the spacecraft, which was the first to orbit Mercury, captured some 270,000 images of the planet during its four-year mission. The website also said the impact will create a 52-foot-wide crater in Mercury’s surface.
The spacecraft made several big discoveries during its mission, including the presence of ice in some dark craters near the poles, according to The New York Times. That’s pretty big news on a planet that reaches temperatures as high as 800 degrees Fahrenheit during the day.
The mission ended, according to NASA, because the spacecraft’s thrusters have run out of fuel.

SAN FRANCISCO (CBS SF) — An active undersea volcano off the Oregon Coast has apparently begun a new eruption — an event which was predicted by two scientists months ago.
Based on a swarm of thousands of earthquakes and a seafloor drop of 8 feet, the eruption of the submarine volcano called Axial Seamount commenced on April 24.
The apparent eruption was observed by scientists in real time, with the help of high-tech instruments installed by scientists at the University of Washington.
“It was an astonishing experience to see the changes taking place 300 miles away with no one anywhere nearby, and the data flowed back to land at the speed of light through the fiber-optic cable connected to Pacific City — and from there, to here on campus by the Internet, in milliseconds,” Washington oceanogoraphy professor John Delaney said in a statement.
The volcano is located along the boundary between two tectonic plates — the Pacific Plate and the Juan de Fuca plate — about 300 miles west of Oregon.
In a blog post last autumn, Bill Chadwick of Oregon State University and Scott Nooner of the University of North Carolina at Wilmington predicted that the Axial Seamount would erupt within the next 15 months based on a repeated pattern of seafloor elevation changes before, during, and after eruptions dating back to 1998.
Scientists say the activity is not strong enough to be felt on land nor is it likely strong enough to produce a tsunami.

Many things would be difficult about conducting a manned mission to Mars, from designing a spacecraft that could make the 34-million-mile journey, to stocking and fueling it, to keeping its astronauts from getting flabby and bored.
On Friday, researchers shed light on another potential hurdle: figuring out a way to protect travelers’ brains from the damaging effects of cosmic rays in outer space.
When University of California, Irvine neuroscientist Charles Limoli and colleagues exposed mice to radiation similar to that astronauts would encounter far beyond Earth, the animals experienced changes in their brains that impaired their performance on tests of learning and memory, the team reported in an article — “What happens to your brain on the way to Mars” — in the journal Science Advances.
The researchers’ results suggested that astronauts could suffer cognitive impairment during an extended journey through space.
“Over the course of a two- to three-year mission, the damage would accumulate,” Limoli said. “To mitigate it, we need to understand it.”
To test the effects of space radiation on the brain, the researchers took mice to the NASA Space Radiation Laboratory at the Brookhaven National Laboratory in New York, which attempts to simulate radiation conditions in space. They exposed the animals to oxygen and titanium ions, atoms with their electrons stripped away that are similar to the charged particles in cosmic rays.
Six weeks later, back in California, they tested the mice’s learning and memory by placing them in pens with toys, letting them get used to their surroundings, and then making changes such as introducing a new toy. Mice that had been exposed to the radiation were less aware of or curious about the changes in their environment than controls that had not been irradiated — a sign that they had cognitive deficits.
“A smart animal will recognize the change,” Limoli said.
When the researchers later studied the animals’ brain tissue, they found that mice that performed poorly on the tests also had less dense branching in their brain cells, due to damage from the radiation. The structural changes would impede the brain’s ability to transmit signals and process information.
Limoli got involved in the NASA-backed research as an outgrowth of his work on the effects of radiation on brain cancer patients. Radiation therapy forestalls brain cancer progression, he said — but it can take a tremendous toll on the central nervous system, causing depression, anxiety and mood disorders, and deficits in learning and executive function. Pediatric patients can lose 20 to 30 I.Q. points after receiving radiation treatments to the brain.
“Doctors have gotten really good at curing cancer, but maintaining a good quality of life has been a problem,” Limoli said. “This is an unmet medical need.”
Astronauts flying to Mars and getting hit by cosmic rays, which are the remnants of supernova explosions, wouldn’t get anything close to the high doses of radiation that cancer patients receive, but they “might be prone to mistakes,” Limoli thought.
To counteract that threat during planning for a possible mission, scientists might come up with more advanced shielding options — perhaps embedded in helmets — or drug treatments that might ameliorate radiation’s impacts on the brain, similar to the ones Limoli is exploring for cancer patients.
