"It is your attitude, not your aptitude, that determines your altitude."

–Hilary "Zig" Ziglar (1926-2012)

Time to add some Nelly to your 4th of July playlist because it really is getting hot in here.

An estimated 250 million Americans are expected to face dangerous temperatures this holiday weekend, as a major heat wave settles over much of the US.

The heat index, or what it actually feels like outside once humidity is factored in, is forecast to soar over the next three days. More than 100 daily high-temperature records could fall through Saturday, along with ~250 record-warm overnight lows.

• Some of America’s biggest cities are expected to continue seeing heat indices reach dangerous levels today, including Chicago (101°), Detroit (105°), New York City (112°), Philadelphia (109°), Washington, D.C. (111°), and Nashville (112°).
• Triple-digit heat indices are expected to linger across much of the Midwest, South, and Northeast through the holiday weekend.

The plan to beat the heat

Cities across the country are already rolling out heat-response plans, including deploying new cooling centers and "cool vans" stocked with water, electrolytes, sunscreen, and meals.

• Some Northeast transit systems are slowing trains to reduce heat-related equipment problems.
• Electric utilities in some areas are also urging customers to conserve energy by setting thermostats no lower than 78 degrees to help prevent outages.

In the know: Extreme heat is the deadliest weather-related hazard in the US, with at least 13,000 heat-related deaths reported since 2018, according to the CDC. The National Weather Service recommends drinking plenty of fluids, staying in air-conditioned spaces when possible, limiting time in the sun, and checking in on older relatives, neighbors, and anyone who lives alone.

Looking ahead…Track the heat wave in real time to find out how hot it’ll feel in your area before heading outside this holiday weekend.

Summer means more opportunity for UV exposure, the #1 driver of visible skin aging. More than stress, sleep, or genetics. A single exposure can trigger collagen breakdown for up to 7 days, leading to the fine lines, sagging, and loss of firmness that show up on your skin over time.

SPF protection alone doesn't address UV damage already done – that's where OneSkin’s OS-01 Peptide comes in. It’s proven to reverse the visible effects of UV aging, going further than any SPF can on its own.*

OneSkin's limited-edition summer bundles pair peptide-powered sunscreens with their bestselling OS-01 skincare, building a complete system for keeping skin visibly smooth, firm, resilient, and protected all summer long.

The next Swift comeback tour won't require a battle with Ticketmaster, but rather a state-of-the-art $30 million spacecraft and rocket launch.

NASA is preparing to launch a first-of-its-kind robotic rescue mission to save its Swift Observatory, a $500 million space telescope that’s currently falling back down to earth after 20 years in orbit.

• Recent solar activity has increased atmospheric drag on the aging spacecraft, and because it wasn't built with thrusters or designed to be serviced, it can't raise its own orbit.
• If left alone, the space telescope is projected to burn up in Earth's atmosphere later this year.

But NASA won’t let that happen without a fight

The space agency’s mission centers around a robotic servicing spacecraft called LINK, which is set to launch into space as early as 4:09 am CT this morning.

• After several weeks of testing, LINK will approach Swift, grab the telescope using three robotic arms, and use ion thrusters to slowly raise Swift’s altitude and prevent it from re-entering Earth’s atmosphere.
• The entire rescue mission is expected to cost NASA around $30 million.

History in the making: If LINK successfully captures Swift, it would mark the first time a commercial spacecraft has docked with and rescued a government satellite that was never designed to be serviced. This capability could one day help extend the lives of other aging satellites and spacecraft, instead of replacing them.

Looking ahead…NASA expects the rendezvous, capture, and gradual process of raising Swift’s orbit to unfold over the next several months.
