Elon Musk Is Trying To Launch A Car Playing David Bowie Into Space This Afternoon

first_imgElon Musk is a fascinating figure, acting as the CEO and lead designer at SpaceX in addition to heading a number of other companies including Tesla, Neuralink, and others. Today, SpaceX will launch of their unmanned rocket, Falcon Heavy, into Earth’s atmosphere for the first time. As told by CNN, if the launch is successful, Falcon Heavy “will become the world’s most powerful operational rocket. … With its 27 engines, the rocket will give off a thrust equal to 18 Boeing 747 jetliners … [and] will be capable of sending humans to the moon or Mars.” The launch is planned for 1:30 p.m. EST.According to The Verge, if the multi-stage launch is successful, the Falcon Heavy’s final booster will split in half and release its payload–a Tesla Roadster–into space on a hyperbolic route toward Mars (and beyond) at around seven miles per second. As Musk claimed in a tweet back in December, the Tesla “will be in deep space for a billion years or so if it doesn’t blow up on ascent.Elon Musk also said in the tweet that the Roadster’s stereo would play David Bowie‘s “Space Oddity” as it makes its way toward a Mars orbit. Yesterday, ahead of the launch of the Falcon Heavy, SpaceX released an animation of the anticipated launch backed by Bowie’s “Life On Mars?” You can watch the animated video below:[Video: SpaceX]While no sounds can be heard in the vacuum of outer space regardless, there’s something satisfying about knowing that SpaceX’s Mars-bound car will be blasting David Bowie as it flies through the solar system.

Cotton Diseases

first_imgIn addition to root-knot nematodes and target spot disease, Georgia cotton farmers should be prepared to fight bacterial blight, said University of Georgia Cooperative Extension plant pathologist Bob Kemerait.Kemerait advises producers, specifically those who farm in fields with a history of bacterial blight, to consider planting resistant varieties and managing the residue from last year’s crop. Farmers could also rotate the affected field away from cotton for at least one season.Infected seed can also spread bacterial blight.“Like we saw last year, there were fields where cotton production hadn’t occurred in many years and bacterial blight showed up to a small degree. How did it get there? One of the possible reasons is that it came in on the seed,” Kemerait said.Bacterial blight, also known as angular leaf spot because of the characteristic geometric shape of the leaf lesions, causes water-soaked lesions on cotton bolls. The lesions are often most prominent at the base of the boll. The disease has been more problematic the past two growing seasons. Significant defoliation and boll rot were reported in the most affected fields.“Bacterial blight is very much on the minds of our growers. In 2016, it was not severe or yield-limiting in most places, but there were some areas, especially in southwest Georgia, where yield losses did occur due to this disease,” Kemerait said.No effective control product is available for growers to spray to control the disease, he said. Management tactics have to be employed before the cotton crop is planted.Planting a bacterial-blight-resistant variety is one control method, but it comes with risks, Kemerait said.“Growers should carefully consider a number of factors in addition to bacterial blight resistance when selecting a cotton variety,” Kemerait said. “There may be other, more desirable varieties, such as ones with nematode resistance or higher yield potential.”Root-knot nematodes, which are microscopic worms, also threaten Georgia’s cotton production. They attack the plants’ roots, causing swollen galls to form in response to the infection. The knots serve as feeding sites where the nematodes grow and lay eggs. This stunts the plant’s growth.Kemerait advises farmers to select a cotton variety based on past problems they’ve experienced in their fields.“If you were significantly impacted by bacterial blight in 2015 or 2016, or you simply find any level of bacterial blight unacceptable, then you may want to select a variety with increased bacterial blight resistance and manage nematodes, if necessary, with nematicides,” Kemerait said.He advises growers not to lose sight of other diseases, especially target spot disease. Target spot disease, or corynespora, begins as a small spot and develops into white lesions with the characteristic, target-like concentric circles on them. At this state, the plants begin to defoliate rapidly.“Heading into this year, there’s no doubt target spot is an issue that we need to be concerned with. Not every grower in the state needs to make fungicide applications to manage it, but every grower should be aware of the disease, be aware of which fungicides are labeled for control and when to apply the treatments,” Kemerait said. “Growers who have had high yield potential and high disease pressure in the past, especially in southwest Georgia, are most at risk.”For more information about Georgia’s cotton crop, go to www.ugacotton.com.last_img read more
