Despite what so many people would love to believe,NASA hasn't discovered any evidence of past or present intelligent life on Mars. Therefore, when the Curiosity rover (好奇号探测器)found something suspicious on the Red Planet's surface, they were not only surprised but also a little bit worried.
The thin fragment (碎片)was suspicious enough to guarantee its own name, with NASA's Curiosity rover team calling it the “Pettegrove Point Foreign Object Debris,” named for where it was discovered. With no idea what it was or where it came from, the rover's handlers began to worry that it might actually be a piece of the rover itself,suggesting some unseen damage or other issue with the robot. Thankfully,those concerns seem to have been unfound.
In a new update from NASA the object has now been identified as a natural piece of rock rather than a piece of any man-made craft or vehicle. The team analyzed the unusual object with a tool called the Chem Cam RMI. The instrument uses a laser (激光器)to sniff out the makeup of anything that is pointed at, and the results for this particular piece of debris revealed that it's actually just a very thin piece of rock.
NASA describes the inspection: The planning day began with an interesting result from the previous plan's Chem Cam RMI analysis of a target that was referred to as “Pettegrove Point Foreign Object Debris”(PPFOD),and supposed to be a piece of spacecraft debris fact. In fact it was found to be a very thin slice of rock, so we can all rest easy tonight. Curiosity has not begun to shed its skin!
How this particularly thin sliver of rock got to where it is—and why it seems to be a different colour than the surrounding sand and debris—remains unexplained, but at least the rover isn't falling apart.
Are You a Morning Person?
Mornings are not for everyone. Knowing that our own bodies may be wired to prefer a certain time of day is certainly a relief. But many of us still have to wake up and function during those first daylight hours. So what can you do?
We tapped a variety of experts—from sleep experts to nutritionists to life organizational pros—to share their tricks on how to make morning less stressful and more pleasant (for) even the most after-hours of night owls.
①Night waking
Poor sleep quality can explain why we sometimes wake up from eight hours of snoozing and feel like we only clocked in at four. "It's normal to have one or two awakenings, but more than that leaves us feeling groggy in the morning because of the fragmented sleep," [explains Shelby Harris, director of the behavioral sleep medicine program at Montefiore Medical Center.]
②The Science of snoozing
The snooze button does more harm than good. Nodding off again sends you into a light and fragmented sleep! Multiple snoozes can leave you feeling groggier than just getting out of bed the first time.
Instead, be honest about the time you intend to get up and then enjoy every last minute of shuteye, so you can wake up alert and ready to go.
③Don't ease into your workday
It can be tempting to plow through the easy things early on-checking e-mail, scanning the headlines—but it's wise to tackle the bigger stuff first. "Getting to work on the most important tasks not only ups the chances that they actually get done, but it also leaves you with a burst of accomplishment to take with you the rest of the day," says Jason Selk, coauthor of Organize Tomorrow Today.
④Save social media for later
Schedule a social media block later in the afternoon to check in when you're likely to need a break anyway, and save the morning for the important stuff.
